• rs12345 Help.ShowHelp locking up

  I am having strange behavior using HTML help in an application... My application is an specialized editor, and when a user highlights text in the editor and then presses <F1>, I want to open up an HTML help file, to the appropriate topic.   So my code on the form inside the event looks like this... Help.ShowHelp(Me, HelpFileLocation, HelpNavigator.KeywordIndex , SelectedText) It works great when there is only one topic in the help file's index for the selectedtext.  When there is more than one topic for that keyword, an additional dialog opens entitled "Topics Found", which does display the multiple topics as expected.  The problem is that this window (and now my application) are completely locked up, lea ...Show All

• hvdtol use of DataGridViewCellCancelEventArgs on 2 grids causes a lock up

  I have two datagrids on a form and they both use the  DataGridViewCellCancelEventArgs  To set the e.cancel to true if data valdiation fails, however if the focus is going from the grid to anything other than the other grid and the validation fails then setting e.cancel to true works fine however if focus would be going to the other datagrid then setting e.cancel will cause a lock up (infinite loop that is not traceable).  Any ideas   ...Show All

• RyuMaster Put a glass panel over form while processing?

  Dear all What i would like to achieve is placing something like a glass panel over the form while is doing some processing and show a proress bar. Little something like that , which would informa the user that something is happening:) Any ideas or advice Is there any code examples Cheers Why not use another form rather than a panel. Set the opacity to 1%, give it the same text, size and location as the form doing the processing. You could also make it TopMost if you wanted to be really annoying. (1) 0x20 is WS_EX_TRANSPARENT (from C's "WinUser.h" file) (2) It should be cp.ExStyle |= 0x20; (ie use the OR operator rather than adding it.) ...Show All

• Mr_White Fire events outside the form (KeyPress)

  Hi, I need to know how can I be able to fire an event outside of my form. We all know that there are lots of events that are fired by some action of some control or the form, such as Form1_Load, Form1_KeyPress, Button1_Click, Timer1_Tick, etc..., but to be more specific I really needed to (sort of) fire the KeyPress event outside the form. Let me simplify this: Suppose I have a form with a textbox, and I have the Form1_KeyPress event to capture the keys I press within the form, and individually transforming them to different keys, by changing the content of the e.KeyChar value while the KeyPress event is running, thus changing its output. To put it simple, the program basically transforms the pressed keys into different ones. For examp ...Show All

• Gaurav Arora disabling click event while a process is running

  I would like to start a new process (.exe application) from my form when a button is clicked. I dont want to get back to my form till the application exits. So I use waitforexit(). However if I click on the button in the form when the application is running, the click event is stored and when the application ends the event is processed and the application starts again. How do I get any click events that occurs on the form to be ignored when another application is running Don't use WaitForExit() but just set a boolean flag that the process is running. Ignore clicks while that flag is set. Implement the Process.Exited event to reset the flag back to False. Please yell if you need cod ...Show All

• Tridex Problems with a DataGridVew with a DataGridViewComboBoxColumn

  My objective is that a field value in Column1, a DataGridViewTextBoxColumn, selects the items listed in Column2, a DataGridViewComboBoxColumn.
