I'm trying to add a bmp picture in picture controle in my dialog based app.
So basically I have added picture control in dialog, and I have changed picture control type from frame to bitmap. Picture control ID is IDC_STATIC
After that I added this code in header:
CStatic* m_picture;
In project file under OnInitDialog I added this:
m_picture = (CStatic *)GetDlgItem(IDC_STATIC);
HITMAP hb = (HBITMAP)::LoadImage(NULL, L"C:\1.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
m_picture->ModifyStyle(0xF, SS_BITMAP, SWP_NOSIZE);
m_picture->SetBitmap(hb);
I don't get any errors, however the app doesn't work, it doesn't display anything...
Am I missing something?
I think Your Path is not relevant
TO add Image to a Picture Control
// Declare CStatic Object
CStatic aDummyImageName;
//On InitFunction
BOOL YourClassName::OnInitDialog()
{
aDummyImageName= (CStatic*)GetDlgItem(ID of Your Picture Control);
HBITMAP dateImage = (HBITMAP)LoadImage(NULL, L"Path of the Image", IMAGE_BITMAP, 225, 170, LR_LOADFROMFILE);
aDummyImageName->SetBitmap(dateImage);
return TRUE;
}
Try This, It Will Work
IDC_STATIC is used for everything that doesn't change. The program can't find it with that. But once you fix that you may have MY problem, which is that Visual studio keeps revising my picture control in *.rc to no longer be "static", and then it won't build. :(

I'm trying to capture whole desktop screen (front buffer) and add a logo and caption to each frame.
I load the logo (.png or .jpeg file) as IDirect3DTexture9 and I try to add it to a IDirect3DSurface9 image frame (screenshot).
As I'm new to DirecX9, I have no idea how to copy the logo (texture) to the screenshot (surface/buffer). Any help would be appreciated.
(If there's any other way to add logo to each frame without involving texture, please do tell me.)
EDIT:
I have used the code suggested in an answer below. The hr result returned is an error.
IDirect3DSurface9 *pSurface = NULL;
pDevice->GetFrontBufferData(0, pSurface); //my screenshot
LPDIRECT3DTEXTURE9 tex = NULL; //my logo
//[code to load logo from file here]
IDirect3DSurface9 *pSurf = NULL;
tex->GetSurfaceLevel(0, &pSurf);
hr = pDevice->StretchRect(pSurf, NULL, pSurface, NULL, D3DTEXF_NONE); //HR GIVES AN ERROR
You can use StretchRect.
The code will look something like this (pseudo):
ID3DSurface9 *pScreenSurface = ... // your screenshot surface should be created in default pool and the same format as your texture(see bellow), like this:
CreateOffscreenPlainSurface(width, height, D3DFMT_X8B8G8R8, D3DPOOL_DEFAULT, &pScreenSurface, NULL);
// Now get a screenshot by using either GetFrontBufferData, or GetBackBuffer/GetRenderTargetData by supplying pScreenSurface as a parameter (not shown here).
ID3DTexture9 *pTexture = ... // your texture should be loaded in default pool and the same format as your screenshot surface, like this:
D3DXCreateTextureFromFileEx(*ppDevice, L"icon.bmp", 40, 40, D3DX_DEFAULT, 0,
D3DFMT_X8B8G8R8, D3DPOOL_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, 0, NULL,
NULL, &pTexture);
ID3DSurface9 *pSurf;
pTexture->GetSurfaceLevel(0, &pSurf); // don't forget to Release pSurf after StretchRect
RECT rc = { ... initialize the destination rectangle here };
pDevice->StretchRect(pSurf, NULL, pScreenSurface, &rc);
You need to specify a destination rectangle inside the destination surface, where you want your texture to be copied.
I am trying to create a notification Icon based application in which I want to display some numbers ranging from 1-999.
I looked at this video which is similar to what I want to do but here the system tray icon just displays the icon and it shows a pop up rather than the system tray icon showing the number or any text.
Excluding the popup item, all I want to do is to read a number (input from somewhere) and display that number in the notification icon section.
I am open to trying any technology (QT, .net) for doing this. Basically, I am looking for some examples.
While parts of your question are vague, this is very possible, I'd even dare-say quite simple. Since you mentioned you're open to trying any technology, C# would probably simplify things for you.
Generate a new 16 x 16 Bitmap and draw the number to it using the Graphics class.
Convert the Image instance to an Icon instance, after disposing of your Graphics object.
Set the Icon property of your NotifyIcon to the icon you've just created.
These are the basic steps. You'll likely need to do some research if you aren't familiar with the classes used.
Thanks for replying to my question. Here is what I came up with. Not sure if this is what you were talking about.
Bitmap bmp = new Bitmap(WindowsFormsApplication2.Properties.Resources._16by16BitmapIcon);
RectangleF rectf = new RectangleF(2, 2, 16, 16);
Graphics g = Graphics.FromImage(bmp);
g.DrawString("99", new Font("Tahoma", 7), Brushes.Blue, rectf);
pictureBox1.Image = bmp;
pictureBox1.Height = bmp.Height;
pictureBox1.Width = bmp.Width;
g.Dispose();
var thumb = (Bitmap)bmp.GetThumbnailImage(64, 64, null, IntPtr.Zero);
thumb.MakeTransparent();
notifyIcon1.Icon = Icon.FromHandle(thumb.GetHicon());
Now my next question could this be done in a better way? This is my first C Sharp app so any suggestions are welcome!
public void ShowText(string text, Font font, Color col)
{
Brush brush = new SolidBrush(col);
// Create a bitmap and draw text on it
Bitmap bitmap = new Bitmap(16, 16);
Graphics graphics = Graphics.FromImage(bitmap);
graphics.DrawString(text, font, brush, 0, 0);
// Convert the bitmap with text to an Icon
Icon icon = Icon.FromHandle(bitmap.GetHicon());
m_notifyIcon.Icon = icon;
}
I am relatively new to the Win32/Windows API (non-MFC), and am trying to change the text colour of a static text control. It is already drawn to the screen in black, but I want to change it to another colour using the Windows Colour Chooser dialog, which is opened on clicking a button. Is this possible?
For the button, the WM_COMMAND message is handled on clicking. So far, I have written:
CHOOSECOLOR ccColour;
ccColour.lStructSize = sizeof(ccColour);
ccColour.hwndOwner = hWnd;
ccColour.rgbResult = crLabelTextColour;
ccColour.Flags = CC_FULLOPEN | CC_RGBINIT;
if (ChooseColor(&ccColour) == TRUE)
{
// crLabelTextColour is a COLORREF global variable assigned on loading the program
crLabelTextColour = ccColour.rgbResult;
}
This code, however, fails with an unhandled exception at the if statement, and I'm not sure why! Other examples seem to write code like this.
ChooseColor() crashes because you are not initializing the CHOOSECOLOR structure completely. You are only setting 3 fields, the rest will contain garbage. You'll need to zero-initialize everything, simple to do:
CHOOSECOLOR ccColour = {0};
I just started to use dialogs and I really like the possibility to define the layout in resource file. But is it possible to set up one dialog and embed it into another (i.e., no floating dialogs)?
With plain windows, I created the main window with one child window. Then, I created even more windows (like "edit", "static", ...) and added them to the child. I did so in order to group those several windows in to one window so I can control, say, the visibility of all edits and statics easily. Kind of like grouping (but it doesn't have the border of GroupBox).
Is it possible to rewrite the above, but with dialogs written down in .rc file?
I'm using plain C and Win32.
Example of what I did:
main = CreateWindow(...);
container = CreateWindow(... hWndParent = main ...);
label = CreateWindow("static", ... container);
edit = CreateWindow("edit", ... container);
Now, if I can hide or resize both label and edit just but controlling container.
Example of what I would like to have:
MAIN_DIALOG DIALOG 10, 20, 30, 40 STYLE ...
BEGIN
CONTROL "container" ...
END
How do I add 'label' and 'edit' to "container" control?
Also, in the resource editor set the dialog style to 'child' and border to 'none'.
What you want to do is probably a little bit similar to tabbed dialogs. There some controls are embedded from separate resources with a outer dialog. You can then show/hide all the controls within a tab by calling ShowWindow just for the subdialog:
In you main dialog Callback add something like
HWND SubDlgHwnd; // Global or probably within a struct/array etc.
case WM_INITDIALOG:
{
HRSRC hrsrc;
HGLOBAL hglobal;
hrsrc = FindResource(sghInstance, MAKEINTRESOURCE(SubDlgResId), RT_DIALOG);
hglobal = ::LoadResource(sghInstance, hrsrc);
SubDlgHwnd = CreateDialogIndirect(sghInstance, (LPCDLGTEMPLATE)hglobal, hDlg, ChildDialogCallback);
SetWindowPos(SubDlgHwnd, HWND_TOP, x, y, 0, 0, SWP_NOSIZE);
break;
}
case WM_COMMAND:
{
...
if(UpdateVisibility)
ShowWindow(SubDlgHwnd, showSubDialog ? SW_SHOW : SW_HIDE);
}
This might be a good Startpoint for Microsofts documentation.
You also have to add DS_CONTROL style to the dialog(s) you want to embed. Without it embedded dialog window will be shown with window header what is hardly one wants to.
I followed this tutorial (there's a bit more than what's listed here because in my code I get a window via mouse click) for grabbing a window as a bitmap and then rendering that bitmap in a different window.
My question:
When that window is minimized or hidden (SW_HIDE) my screen capture doesn't work, so is it possible to capture a window when it is minimized or hidden?
The PrintWindow api works well, I use it for capturing thumbnails for hidden windows. Despite the name, it is different than WM_PRINT and WM_PRINTCLIENT, it works with pretty much every window except for Direct X / WPF windows.
I added some code (C#) but after reviewing how I used the code, I realized that the window isn't actually hidden when I capture its bitmap, its just off screen so this may not work for your case. Could you show the window off screen, do a print and then hide it again?
public static Bitmap PrintWindow(IntPtr hwnd)
{
RECT rc;
WinUserApi.GetWindowRect(hwnd, out rc);
Bitmap bmp = new Bitmap(rc.Width, rc.Height, PixelFormat.Format32bppArgb);
Graphics gfxBmp = Graphics.FromImage(bmp);
IntPtr hdcBitmap = gfxBmp.GetHdc();
bool succeeded = WinUserApi.PrintWindow(hwnd, hdcBitmap, 0);
gfxBmp.ReleaseHdc(hdcBitmap);
if (!succeeded)
{
gfxBmp.FillRectangle(new SolidBrush(Color.Gray), new Rectangle(Point.Empty, bmp.Size));
}
IntPtr hRgn = WinGdiApi.CreateRectRgn(0, 0, 0, 0);
WinUserApi.GetWindowRgn(hwnd, hRgn);
Region region = Region.FromHrgn(hRgn);
if (!region.IsEmpty(gfxBmp))
{
gfxBmp.ExcludeClip(region);
gfxBmp.Clear(Color.Transparent);
}
gfxBmp.Dispose();
return bmp;
}
There are WM_PRINT and WM_PRINTCLIENT messages you can send to the window, which cause its contents to be rendered into the HDC of your choice.
However, these aren't perfect: while the standard Win32 controls handle these correctly, any custom controls in the app might not.
I am trying to get the bitmap of partially hidden controls.
I used code before that did the drawing, but included windows overlapping it. So.. maybe you want to try this.
The WM_PRINTCLIENT should (in my understanding) redraw all inside the control, even if it is not really visible.
const int WM_PRINT = 0x317, WM_PRINTCLIENT = 0x318, PRF_CLIENT = 4,
PRF_CHILDREN = 0x10, PRF_NON_CLIENT = 2,
COMBINED_PRINTFLAGS = PRF_CLIENT | PRF_CHILDREN | PRF_NON_CLIENT;
SendMessage(handle, WM_PRINTCLIENT, (int)hdc, COMBINED_PRINTFLAGS);
//GDIStuff.BitBlt(hdc, 0, 0, width, height, hdcControl, 0, 0, (int)GDIStuff.TernaryRasterOperations.SRCCOPY);
The before code is commented out now. It is based on the code found here: Pocket PC: Draw control to bitmap (accepted answer). It is basically the same as Tim Robinson suggests in this thread.
