I am using C++ and plain Winapi calls to display Print dialog box and it works fine. However the dialog box I get shows old printer icons compared to similar Print dialogs produced by other software. I wonder why.
Does anyone have an idea how to display the new printer icons as does MSVC dialog
Thanks a lot.
Here is how I display the Print Dialog in my application:
// Initialize the PRINTDLGEX structure
PRINTDLGEX PrnDlgEx ;
PrnDlgEx.lStructSize = sizeof (PRINTDLGEX) ;
PrnDlgEx.hwndOwner = hwnd ;
PrnDlgEx.hDevMode = NULL ;
PrnDlgEx.hDevNames = NULL ;
PrnDlgEx.hDC = NULL ;
PrnDlgEx.Flags = PD_HIDEPRINTTOFILE | PD_NOCURRENTPAGE | PD_NOPAGENUMS |
PD_NOSELECTION | PD_USEDEVMODECOPIESANDCOLLATE ;
PrnDlgEx.Flags2 = 0 ;
PrnDlgEx.ExclusionFlags = 0 ;
PrnDlgEx.nPageRanges = 0 ;
PrnDlgEx.nMaxPageRanges = 0 ;
PrnDlgEx.lpPageRanges = nullptr ;
PrnDlgEx.nMinPage = 1 ;
PrnDlgEx.nMaxPage = 0xFFFF ;
PrnDlgEx.nCopies = 1 ;
PrnDlgEx.hInstance = NULL ;
PrnDlgEx.lpPrintTemplateName = NULL ;
PrnDlgEx.lpCallback = NULL ;
PrnDlgEx.nPropertyPages = 0 ;
PrnDlgEx.lphPropertyPages = NULL ;
PrnDlgEx.nStartPage = START_PAGE_GENERAL ;
PrnDlgEx.dwResultAction = 0 ;
HRESULT Result = PrintDlgEx (&PrnDlgEx) ;
Below is screen shoots for my Print dialog 1 and MS VC dialog 2.
According to Customizing the Print Dialog Box.You can create the custom template by modifying the default template specified in the Prnsetup.dlg file. The control identifiers used in the default Print dialog template are defined in the Dlgs.h file.
Then use the PRINTDLG structure to enable the template.

So, I'm calling GetFileSaveName from some C code. The C code is called from PowerBuilder, but I really don't think that is relevant.
On just one user's computer currently (Windows 10, updates done), it returns 0, then CommDlgExtendedError return 65535 (CDERR_DIALOGFAILURE), which the docs say means "The dialog box could not be created. The common dialog box function's call to the DialogBox function failed. For example, this error occurs if the common dialog box call specifies an invalid window handle."
I know that the common dialogs aren't completely broken on her PC - I can pull up a File Open or Save dialog in Notepad, for instance.
I had a bug in my code giving the same error number in the past, where in the OPENFILENAME structure I passed in to GetOpenFileName I had set the hWndOwner variable to a handle to a window that no longer exists, but in this case it is being set to 0, so that's not the problem.
The same code is working for thousands of other users of our software! Any bright ideas what could be going on? Thanks.
OK, people have asked me to post my code initializing the OpenFileName structure. It's PowerScript (PowerBuilder's coding language) but should be pretty comprehensible).
OPENFILENAME iOFN
CONSTANT long CHARSIZE = 2
aul_flags = OFN_HIDEREADONLY + OFN_EXPLORER +
OFN_FILEMUSTEXIST+ OFN_NOCHANGEDIR + OFN_DONTADDTORECENT
RtlZeroMemory(iOFN, ll_sizeof)
// initialize structure
iOFN.lStructSize = ll_sizeof
iOFN.nFilterIndex = 1
iOFN.nMaxFile = MAX_LENGTH
iOFN.hWndOwner = il_hWnd
iOFN.Flags = aul_flags + OFN_ENABLESIZING /* needed when using hook procedure */
// allocate memory and copy title
ll_length = Len(as_title) * CHARSIZE
iOFN.lpstrTitle = LocalAlloc(LMEM_ZEROINIT, ll_length + 2)
RtlMoveMemory(iOFN.lpstrTitle, as_title, ll_length)
// allocate memory and copy filter
this.of_Parse(",", as_filter, ls_filter)
li_max = UpperBound(ls_filter) /* count of 1-based array elements */
For li_cnt = 1 To li_max
ll_length = this.of_StringToChar(Trim(ls_filter[li_cnt]), lc_filter)
Next
ll_length = UpperBound(lc_filter) * CHARSIZE
iOFN.lpstrFilter = LocalAlloc(LMEM_ZEROINIT, ll_length)
RtlMoveMemory(iOFN.lpstrFilter, lc_filter, ll_length)
// allocate memory and copy default extension (if given)
If as_extension <> "" Then
ll_length = Len(as_extension) * CHARSIZE
iOFN.lpstrDefExt = LocalAlloc(LMEM_ZEROINIT, ll_length)
RtlMoveMemory(iOFN.lpstrDefExt, as_extension, ll_length)
End If
// allocate memory and copy initialdir (if given)
If as_initdir <> "" Then
ll_length = Len(as_initdir) * CHARSIZE
iOFN.lpstrInitialDir = LocalAlloc(LMEM_ZEROINIT, ll_length)
RtlMoveMemory(iOFN.lpstrInitialDir, as_initdir, ll_length)
End If
// allocate memory for returned data
lc_pathname = Space(MAX_LENGTH)
iOFN.nMaxFile = MAX_LENGTH
iOFN.lpstrFile = LocalAlloc(LMEM_ZEROINIT, MAX_LENGTH)
If as_initialfile <> "" Then
ll_length = Len(as_initialfile) * CHARSIZE
RtlMoveMemory(iOFN.lpstrFile, as_initialfile, ll_length)
End If
// display dialog box
lb_return = GetOpenFileName(iOFN)
I recommend you to check if there is any problem with the OPENFILENAME parameter configuration. There are many parameters in OPENFILENAME that need to be configured before GetSaveFileName can be used. Maybe there is something wrong.
TCHAR szFilename[MAX_PATH] = TEXT("");
BOOL bResult = FALSE;
DWORD dwError = NOERROR;
OPENFILENAME ofn = { 0 };
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.lpstrFilter = TEXT("All Files\0*.*\0\0");
ofn.lpstrFile = szFilename;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER |
OFN_ENABLEHOOK |
OFN_HIDEREADONLY |
OFN_NOCHANGEDIR |
OFN_PATHMUSTEXIST;
bResult = GetSaveFileName(&ofn);
if (bResult == FALSE)
{
dwError = CommDlgExtendedError();
return dwError;
}
I need to move 'standard_name' to be the first attribute present in all my variables within a netcdf file.
I am yet to find the correct command but I am hoping it will be something fairly straight forward using NCO.
If I ncdump, this is the current output:
short heading(time) ;
heading:data_max = 359.88f ;
heading:long_name = "Ship heading" ;
heading:data_min = 0.f ;
heading:units = "degrees" ;
heading:missing_value = 1.e+38f ;
heading:add_offset = 179.94f ;
heading:standard_name = "ship_heading" ;
heading:scale_factor = -0.005491668f ;
short depth(time, depth) ;
depth:positive = "down" ;
depth:long_name = "Depth" ;
depth:data_min = 20.48f ;
depth:units = "meter" ;
depth:missing_value = 1.e+38f ;
depth:data_max = 572.5f ;
depth:standard_name = "depth" ;
depth:add_offset = 296.49f ;
depth:scale_factor = -0.008423671f ;
I need the output to be :
short heading(time) ;
**heading:standard_name = "ship_heading" ;**
heading:data_max = 359.88f ;
heading:long_name = "Ship heading" ;
heading:data_min = 0.f ;
heading:units = "degrees" ;
heading:missing_value = 1.e+38f ;
heading:add_offset = 179.94f ;
heading:scale_factor = -0.005491668f ;
short depth(time, depth) ;
**depth:standard_name = "depth" ;**
depth:positive = "down" ;
depth:long_name = "Depth" ;
depth:data_min = 20.48f ;
depth:units = "meter" ;
depth:missing_value = 1.e+38f ;
depth:data_max = 572.5f ;
depth:add_offset = 296.49f ;
depth:scale_factor = -0.008423671f ;
I agree that the ideal place for standard_name is as the first or second attribute. Dumps are much more legible that way. You need to understand that attributes are stored and dumped in the order of their creation. NCO has no feature to re-arrange this order. The best solution is to alter the dataset writer so it creates standard_name before all other attributes. Or you can do something crazy like use ncatted to delete all the attributes and then re-add them in your desired order.
I'm building a simple AudioUnit app which should use an AUGraph to connect a generator (which generates, say, a sine wave) to a format converter (because that seems like what I need) to an output device.
Code snippets:
{
AudioComponentDescription desc ;
desc.componentType = kAudioUnitType_Generator ;
desc.componentSubType = kAudioUnitSubType_ScheduledSoundPlayer ;
desc.componentFlags = 0 ;
desc.componentFlagsMask = 0 ;
desc.componentManufacturer = kAudioUnitManufacturer_Apple ;
status = AUGraphAddNode ( mGraph , &desc , &mGeneratorNode ) ;
checkOSStatus ( "creating generator node" , status ) ;
}
I do similarly for mConverterNode with kAudioUnitType_FormatConverter/kAudioUnitSubType_AUConverter and for mOutputNode with kAudioUnitType_Output/kAudioUnitSubType_DefaultOutput.
I then open the graph:
AUGraphOpen ( mGraph ) ; // error checking code omitted from example
I then get references to them:
AUGraphNodeInfo ( mGraph , mGeneratorNode , 0,&mGeneratorRef ) ; // error checking code omitted from example
I then set the format:
{
AudioStreamBasicDescription format ;
format.mSampleRate = mSamplingRate ;
format.mFormatID = kAudioFormatLinearPCM ;
format.mFormatFlags = kAudioFormatFlagIsSignedInteger ;
format.mFramesPerPacket = 1 ;
format.mChannelsPerFrame = 1 ; // mono
format.mBitsPerChannel = 16 ;
format.mBytesPerFrame = format.mBitsPerChannel*format.mChannelsPerFrame/8 ;
format.mBytesPerPacket = format.mBytesPerFrame*format.mFramesPerPacket ;
status = AudioUnitSetProperty ( mGeneratorRef , kAudioUnitProperty_StreamFormat , kAudioUnitScope_Output , kOutputBus , &format,sizeof(format) ) ;
checkOSStatus ( "setting output format" , status ) ;
}
(Note: kOutputBus is an enum to 0; it's an anachronism from a previous example I found. Also, mSamplingRate is a size_t whose value is 48000)
And set the render callback:
{
AURenderCallbackStruct cb ;
cb.inputProc = &_callbackProxy ;
cb.inputProcRefCon = static_cast<void*> ( this ) ;
status = AudioUnitSetProperty ( mGeneratorRef , kAudioUnitProperty_SetRenderCallback , kAudioUnitScope_Output , 0 , &cb,sizeof(cb) ) ;
checkOSStatus ( "setting the generator callback" , status ) ;
}
However, for both the stream format and the render callback I get kAudio_ParamError back as the resultant status.
No matter what I do (mono/stereo, when I place that command, etc), I cannot make it work.
Note: I later do this:
AUGraphConnectNodeInput ( mGraph , mGeneratorNode,0 , mConverterNode,0 ) ;
AUGraphConnectNodeInput ( mGraph , mConverterNode,0 , mOutputNode,0 ) ;
AUGraphInitialize ( mGraph ) ;
AUGraphStart ( mGraph ) ;
// again, error-checking code omitted from example
And it works........ But I can't set those properties and therefore can't generate audio.
What am I missing?
(To people with 1500+ reputation: please make an "osx-sierra" tag; I'm a bit shy of that mark)
From an obscure comment at the end of this:
https://discussions.apple.com/thread/1989797?tstart=0
I ran AUGraphOpen at the very beginning before creating things (why?) and it worked.
But then I was getting invalid format errors, so I set the format on the input of the converter instead of the output of the generator.
But then it wasn't calling the render callback, so I removed the generator altogether and put the render callback on the input of the converter.
At this point, it worked and is generating my sound.
I hope this helps somebody else in the future with this so-horribly-documented API.
I have a VS2010 C++ application that uses the Windows Common File Dialog in a pretty ordinary fashion. My company just updated my workstation to a nice quad core CPU with Windows 7 whereas my previous system was still running XP. When I run my application inside the Visual Studio debugger, any attempt to call the CFD seems to fail silently with the code throwing no apparant errors to the output window, and no dialog appearing. Outside the debugger things work just fine. I invoke the dialog pretty much the same way every time.
CString theFilterList = "CSV Import Files (*.csv)|*.csv";
theFilterList = theFilterList + "|All files (*.*)|*.*||";
// construct the common dialog
CFileDialog fileDlg(TRUE, NULL, NULL,OFN_ENABLESIZING | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT, theFilterList,this);
POSITION pos;
// Initialize m_ofn structure
fileDlg.m_ofn.lpstrTitle = "Please select a UP supplied CSV file to prepare to load into SCT.";
// Create buffer for file names.
const DWORD bufferSize = (MAX_MULTISELECT_FILENAMES * MAX_FILENAMESIZE) + 1;
TCHAR* filenamesBuffer = new TCHAR[bufferSize];
// Initialize beginning and end of buffer.
filenamesBuffer[0] = NULL;
filenamesBuffer[bufferSize-1] = NULL;
// Attach buffer to OPENFILENAME member.
fileDlg.m_ofn.lpstrFile = filenamesBuffer;
fileDlg.m_ofn.nMaxFile = bufferSize;
if ( fileDlg.DoModal() != IDOK)
{
theCSVFilenameList.RemoveAll();
return;
}
pos = fileDlg.GetStartPosition();
while( pos )
{
theCSVFilenameList.Add(fileDlg.GetNextPathName( pos ));
}
I just had this problem. I found that my StackReserve size was too high. I reduced it and the dialog started coming up. Though in my case it was happening both in and out of the debugger.
I would like to know if its possible to WinWaitActive for WindowWithThisTitle and WindowWithThatTitle at the same time. I'm executing a command and there could be a window telling me that the connection failed or a user/pass dialog coming up.
Is there another way doing it as this?
WinWaitActive("Title1", "", 5)
If(WinExists("Title1")) Then
MsgBox(0, "", "Do something")
Else
If(WinExists("Title2")) Then
MsgBox(0, "", "Do something else")
EndIf
EndIf
Because I don't want to have the timeout which could be more than 15 seconds.
A simpler solution might be to use a REGEX title in your WinWaitActive as defined here
You would then have something like this:
$hWnd = WinWaitActive("[REGEXPTITLE:(WindowWithThisTitle|WindowWithThatTitle)]")
If WinGetTitle($hWnd) = "WindowWithThisTitle" then
DoSomething()
Else
DoSomethingElse()
EndIf
How about something like this.
$stillLooking = True
While $stillLooking
$activeWindowTitle = WinGetTitle(WinActive(""))
If $activeWindowTitle == "Title1" Then
MsgBox(0, "", "Do something")
$stillLooking = False
ElseIf $activeWindowTitle == "Title2" Then
MsgBox(0, "", "Do something else")
$stillLooking = False
EndIf
sleep(5)
WEnd
Because I don't want to have the
timeout which could be more than 15
seconds.
WinWaitActive() doesn't have a timeout unless you specify one. You gave it a five second timeout but you could leave that off and it would wait forever.
You can use this Functions for two windows ..

I'm fairly new to autoit and the programming world in general and I had this same dilemma. Luckily I figured out a straight fwd way to do it:
Do
$var1 = 0
If WinGetState("Document Reference","") Then
$var1 = 1
ElseIf WinGetState("Customer Search","") Then
$var1 = 1
EndIf
Until $var1 = 1
So it'll stay in the loop until it finds the window and sets $var1 to 1. There's probably easier ways (I'm sure developers are gasping at this) but this is straight fwd enough for me.
You can create an infinite while loop with if statements in there:
#include <MsgBoxConstants.au3>
Example()
Func Example()
While 1
; Test if the window exists and display the results.
If WinExists("Windows Security") Then
Local $hWnd = WinWaitActive("Windows Security", "", 2000)
ControlSetText($hWnd, "", "[CLASS:Edit; INSTANCE:1]", "hel233")
ControlClick("Windows Security","","[CLASS:Button; INSTANCE:2]")
Sleep(5000)
EndIf
; Test if the window exists and display the results.
If WinExists("Spread the Word") Then
'The line below will wait until the window is active, but we don't need that
'Local $hWnd = WinWaitActive("Spread the Word", "", 2000)
WinClose("Spread the Word")
Sleep(5000)
EndIf
wend
EndFunc
