• mumle .NET app checks for original install location before running?

  It appears that when I install/deploy my .NET 2.0 app using a Deployment Project within my app solution, the first time my app runs it checks the the MyApp.MSI in the location from where the install was originated. Is there any way to prevent this behavior My app is NOT deployed as a ClickOnce app and is not published so I don't understand why this check is happening My deployment files are: Setup.EXE MyApp.MSI CRRedist2005_x86.MSI What I usually do is combine these three files in a single WinZip self extracting to produce an end result of MyAppSetup.EXE. This all works fine with ONE exception, WinZip self extractor will remove the above 3 files from the temp folder it creates. This becomes a problem because when I click on th ...Show All

• MartinHN Scrolling a panel containing graphics

  I actually call this form from another form. When it loads I see it flicker as it paints, but then it just shows up blank. If I click on the form, then it actually redraws the graphics. The main problem I am having is in the scrolling of the panel. When I scroll it ends up a big mess and doesn't work as needed. I know it has something to do with the AutoScrollPosition.X and .Y, but I've added it to the DrawLine methods in the x1, x2, y1, y2 points and still doesn't work the way I am expecting. I just need it to scroll smoothly. Maybe I don't understand the scroll, but I thought I am still technically drawing at zero even if the scrollbar is all the way down and I have to use the scrollbar position to draw the images so it appears as if it ...Show All

• Tobey79 dialog window looses modal state when the main form is resized

  Hi everyone! I have this main form in maximised state from which various dialog windows are launched in modal state. Unfortunately when the main form gets resized (due to the taskbar being resized for example) while one of these modal dialogs is displayed the dialog looses its modality. I discovered this the other day and it is very annoying. Does anyone know a remedy Cheers george Thanks for the reply Peter. This is an example of how i am calling a dialog window. By the way i am using VC++ with .NET 2003 'mainForm' is the application's main form which is always maximized and has a main menu with a member called 'menuItemSimltrs'. 'mainForm' also has an event handler for handling clicks of 'menuItemSiml ...Show All

• ender&amp;#35; How to create a shortcut (ENTER hotkey)

  Hi all, I want to assign a specific shortcut to a button. I cannot see this property in VSTS so I understand is needs to be done in the code. Does anybody have a C# sample to do it Thanks, Bertrand No, a better solution is to set the Forms AcceptButton property to your button. It will now show up as default, and Enter anywhere on the form (except in controls which handle Enter) will press it. Thanks Sean, very nice feature. What if I want to set up ENTER as the hotkey This is correct, but in my case I actually need to perform the ENTER only when the focus is on a particular text box. But I will be more the ninterested to see the Form.AcceptButton code, do you have an example Actually, no c ...Show All
