I have a Dialog that is basically a confirmation dialog on some SQL statements. After the dialog I have an if statement: If frmRelease.ShowDialog() <> Windows.Forms.DialogResult.Cancel then.My buttons are set as DialogResult = OK and DialogResult = Cancel respectively on the dialog form.
For some reason, sometimes my button set to DialogResult = OK is returning me a DialogResult.Cancel, and causing me to skip a block of cleanup code.
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

How can i catch the return of say an OpenDialog/Save Dialog/Color dialog?
For example i want to know if the OK or Cancel button was pressed and use a goto statement that jumps to a section of code that exits the sub to avoid an error (especially in the case of pressing cancel when using an open dialog).
I'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.
In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?
The following code works fine, however if the user wants to cancel out from the openfiledialog they cant they are stuck in a loop. A loop I created in case they selected the wrong type of data file they could choose again. [Code]. I really need some help seeing where and how to let the user cancel out without the program continuing. I tried some dialog.dispose code but everywhere i seem to put it it generates an error somewhere.
View 4 RepliesI have a problem when it comes to faxing html. Im currently using FAXCOMEXLib because I'm sending to a remote fax server. Sending html files causes the function ConnectedSubmit to display a print dialog box before sending the fax. The application hangs when you try to cancel the print dialog box, it seems like the ConnectedSubmit function does not return to previous line where it was called.

View 5 RepliesI'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......

View 5 RepliesI am trying to save multiple text files using a save dialog.
I can save one textbox
SaveFileDialog1.ShowDialog()
Dim File As System.IO.File
Dim Write As System.IO.StreamWriter
Write = File.CreateText(SaveFileDialog1.FileName)
Write.WriteLine(TextBox1.Text)
Write.Close()
but I don't know how to save multiple textboxes and richtext boxes. Would I have to use a screenwriter for this?
If Not IsNumeric(textbox1.Text) Then
KeyAscii = 0
End If
I learned in MSDN and wrote those code,but it doesn't work. This code " KeyAscii = 0" it's not correct, I just want to cancel the input, for instance,if user input 1a, then "a" will be not inputted into textbox, but "1" will leave.
I am trying to save a file as a jpeg. So far the save dialog box opens and it seems to save but I can't open the saved file to see it.
