Below is the code for the new page setting:
Dim newPageSettings As New PageSettings
newPageSettings.Margins = New Margins(20, 20, 20, 20)
newPageSettings.Landscape = True
Dim paperSize As PaperSize = New PaperSize()
paperSize.RawKind = PaperKind.A4
newPageSettings.PaperSize = paperSize
ReportViewer1.SetPageSettings(newPageSettings)
Me.ReportViewer1.RefreshReport()
After I debug the system and click Print Preview in ReportViewer, the screen display as below:
I seriously don't know how this happen. Please help. Thanks.
I have already found a solution for above issue. Instead of using coding to setup setting for print preview, I change the Report Setting in rdlc. Please see below picture for more info:

I've just started working with Windows Forms on Visual Studio 2019. I am most familiar with C++ and thus have been creating an application with C++/CLI. The basis of the project is that I have a schedule generating set of functions these are called in MyForm.h which is the main form originally launched. MyForm.h also opens MyForm2.h when a button is pressed. This MyForm2.h is where I have a problem. I want to allow the user to edit a series of specific settings for the schedule generator. The most user friendly way I've found to do this is with a datagrid using textboxes and checkmarks, but I need to have the original timeslots for the schedule in the datagrid for the user to edit when the open MyForm2.h.
I've looked all over to find how to set default values for a datagrid, but have only come up with two ok methods, both of which have some fatal flaws.
The first was from this microsoft guide.
The problem here is that the solution is written in c#, and I don't know how to implement it in a c++ program.
The second was from a few sites which generally displayed one of two formats which are displayed here in a way that is formatted to how I used them in my forms:
void InitializeComponent()
{
this->dgvStudents = (gcnew System::Windows::Forms::DataGridView());
this->dataGridViewTextBoxColumn1 = (gcnew System::Windows::Forms::DataGridViewTextBoxColumn());
(cli::safe_cast<System::ComponentModel::ISupportInitialize^>(this->dgvStudents))->BeginInit();
this->SuspendLayout();
this->dgvStudents->Columns->Add(this->dataGridViewTextBoxColumn1);
this->dgvStudents->Location = System::Drawing::Point(0, 0);
this->dgvStudents->Name = L"dgvStudents";
this->dgvStudents->Size = System::Drawing::Size(350, 100);
this->dgvStudents->TabIndex = 0;
//
// dataGridViewTextBoxColumn1
//
this->dataGridViewTextBoxColumn1->HeaderText = L"First Name";
this->dataGridViewTextBoxColumn1->Name = L"dataGridViewTextBoxColumn1";
this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
this->ClientSize = System::Drawing::Size(638, 261);
this->Controls->Add(this->dgvStudents);
this->Name = L"MyForm3";
this->StartPosition = System::Windows::Forms::FormStartPosition::CenterScreen;
this->Text = L"Exercise";
(cli::safe_cast<System::ComponentModel::ISupportInitialize^>(this->dgvStudents))->EndInit();
this->ResumeLayout(false);
// Option 1
this->dgvStudents->Rows[0]->Cells[0]->Value = "MLP";
// Option 2
this->dgvStudents->Rows->Add("MLP");
}
I have tried putting both options in several various parts of the InitializeComponent() function and it makes no difference. The problem with Option 2 of this second solution is that it will be removed from the code if I change anything in the [Design] part of the MyForm2.h code editor in VS and save it. Weirdly, Option 1 will not be displayed in the [Design] part of the code and instead I will get the error Member Cells not found in class System.Windows.Forms.DataGridViewRowCollection, but if I launch the debugger for the program, both options will be displayed exactly how I want them to be in the GUIs that appear. As previously meantioned though, both options will most likely be removed if I change anything else in the form designer. Any help would be greatly appreciated:)
At first, please bear with me, as I am quite new to the Delphi world. I am a former C++, C# and embedded developer.
I have Delphi 7 and Delphi RAD Studio 10.2 Starter on Windows 7 64-bit.
I have tried the TGauge component in both versions, as it is standard in Delphi (I think).
So, the issue is when I try to set the Progress property with a value at run-time, it doesn't reflect that on the GUI. But, if I set a value at design-time from the Object Inspector, it reflects the value as it should be, and the Gauge
paints the percentage correctly.
Steps to test this behavior:
Dragged and dropped the TGauge component from the "Samples" palette onto the Form.
I set MaxValue = 100 and MinValue = 0 in the Object Inspector.
I created a textbox (txtValue) on the Form.
I created a button (btnSetValueClick) on the Form and used this code:
procedure TMainForm.btnSetValueClick(Sender: TObject);
begin
Gauge1.Progress := StrToInt(txtValue.Text);
end;
So, I was expecting the Gauge would show the value entered, but it didn't.
When I debug the code, it hits btnSetValueClick() and sets the value inside.
What am I missing here?
EDIT: (This is the code in the form.)
object Gauge1: TGauge
Left = 53
Top = 81
Width = 191
Height = 113
ParentCustomHint = False
Color = clMenu
ForeColor = clRed
Font.Charset = DEFAULT_CHARSET
Font.Color = clBlack
Font.Height = -11
Font.Name = 'Default'
Font.Style = []
Kind = gkNeedle
ParentColor = False
ParentFont = False
Progress = 35
EDIT:
I have created a new project and started from scratch. I put the TGauge without changing any single properties of it. And it has started to work although I don't still see the difference can cause this behavior. At least this might give a clue this component can go wrong without an obvious reason, especially to beginners like me.
Please consider the case is as closed. Thank you.
I'm using visual studio 2013. The text in textbox3 of my program can be edited by the user. I want to fix text in it.To do that user must be unable to edit the text in that textbox. How to do that.
Add following code and you'll get a window with TextBox1 disabled and TextBox2 enabled.
TextBox1.Text = "ContentOfTextBox1" 'fill text box
TextBox1.Enabled = False 'disable text box
or
TextBox1.Text = "ContentOfTextBox1";
TextBox1.Enabled = false;
Set .ReadOnly property to True.As an example,
TextBox1.ReadOnly = True
Here the user can't edit textbox1.
In my javascript, in Windows 7, Photoshop CS2 & Photoshop CS5, it throws an error:
Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
- Could not save a copy as "C:...\wcb-010B-11Y.jpg" because the file could not be found.
Line: 458
-> docRef.saveAs( saveFile, jpgSaveOptions, true, Extension.LOWERCASE );
here is a summary of the code to save the image:
var selectedSaveDir = "~/Desktop/";
var sFileNamePreFix = "wcb-";
var docRef = app.activeDocument;
var docName = app.activeDocument.name;
var docNewName = docName.substr( 0, docName.length - 4 ); // strip file extension
var sNewDocName = sFileNamePreFix + docNewName + ".jpg"
var sNewFileName = selectedSaveDir + sNewDocName;
//alert( "sNewFileName = " + sNewFileName ); // test to verify correct location
var saveFile = new File(sNewFileName);
jpgSaveOptions = new JPEGSaveOptions();
jpgSaveOptions.quality = 12;
docRef.saveAs(saveFile, jpgSaveOptions, true, Extension.LOWERCASE);
In Windows XP, this script works very well in CS2 with no problems.... just in Windows 7 is where this issue occurs using CS2 or CS5.
The problem seems to be similar to : Photoshop Javascript scripting saving and closing document
But I don't know his OS.
I've added the "alert(" and confirmed the save folder & name is correct and can be saved to, but same issue.
Could it be a UAC issue in Windows 7 ? and how do you Fix it ? I've turned off all UAC settings (I think I did it correctly), but it still occurs.
Any Help ?
You missed out " var docRef = app.activeDocument;" (which i've added); but apart from that, in CS2 the script saves out a jpeg to the desktop (wcb-text test.jpg). It's obvious, but have you made sure the image is flattened or doesn't contain any information that cannot be stored in a jpeg - like paths for example.
Try forcing a flatten before saving
//flatten the image
docRef.flatten();
Another thing to try is to save out the file to another directory. I know that long file names (especially with spaces in) can cause problems - I think there's a limit to 300 characters in the file path.
I just found that, in new versions of PS this particular path variable gives the error 8800:
var selectedSaveDir = "~/Desktop/";
Use full path instead and use apostrophes instead of quotes:
var selectedSaveDir = 'C:/Users/yourname/Desktop/';
I have a Visual Studio application with a splash screen image cut into "slices". The positions are specified in the Form Designer so they line up properly on the screen. However, the images are out of place when the application is run on the Chinese version of Windows XP. It looks as if the image slices were "exploded" apart.
What's going on here? Do international versions of Windows have a different meaning of the "top left" coordinate of the picture? How can I force the images to be precisely displayed where I want them?
We found a solution! Apparently the picture boxes stretched out on the Chinese XP PC, but the images they contained did not. The fix was to add code like the following:
Me.PictureBoxIcon.Width = Me.PictureBoxIcon.Image.Width
Me.PictureBoxIcon.Height = Me.PictureBoxIcon.Image.Height
Dim loc As New Point
loc.X = Me.PictureBoxIcon.Location.X
loc.Y = Me.PictureBoxIcon.Location.Y + Me.PictureBoxIcon.Height
Me.PictureBoxAbout.Location = loc
Me.PictureBoxAbout.Width = Me.PictureBoxAbout.Image.Width
Me.PictureBoxAbout.Height = Me.PictureBoxAbout.Image.Height
Hope this helps someone else!
In the OnLoad event of the form, you could always explicitly set the location of each section. If starting at the top left with the first and assuming an array with the images in order:
images[0].Location = new Point(0,0);
for (int i = 1; i < images.Length; i++)
{
images[i].Location = new Point(images[i - 1].Location.X + images[i - 1].Width, 0);
}
That will set the first image to the top left corner and all subsequent images to just after the last image.
