I submitted the same question a few minutes ago, but so far that hasn't appeared in the thread - I wonder why/ - I used the HTML to rite the code I used. When I Click the F5 / Strat Debug on menu the DOS-Based form appears and disappears immediately. I am able to run a DOS-Based program in the computer, I checked this after the Sample Console Application failed to run. The Code I used is given within the Brackets(System.Console.WriteLine("Hello World")).
View 2 RepliesWhen i run the debugging tool for visual basic my computer crashes (Blue screen). it's rather constant with the VB forms, even ones without code at all... Any help on the matter? All the forms were originally built on this computer but don't work any more, they however work fine on other computers so it has to be my computer.
View 7 RepliesI've automated some things on my computer with some mousecommands. This works perfectly. However though when I'm away for a couple of hours and I've got my program running (which is needed) the screensaver won't kick in due to the mouse movements. Is there any way to bypass this? So that a black screen is showed but the program still does its work.
View 1 RepliesI have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?
This is my code to get screen captures every certain interval of time. But each image is being around 150kb and I want to make it smaller. what matters is the image size in kb to be around 70kb ( almost the half ) .

View 5 RepliesExceptions can have different degrees of impact on a program. For example a program should probably abort if OutOfMemoryException is raised, but it is possible to safely and appropriately handle System.Data.SqlClient.SqlException without putting the program in an unknown state.
I do understand that any exception has the potential to put the program in an unstable state if it is not properly handled. Are there exceptions that should never be handled beyond simply logging and throwing up the stack?
FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]
View 13 RepliesI am trying to end a program immediately when a critical exception is caught. But I am finding that code after my Try/Catch block is executing even though the code withing the Catch block is executing, and that Catch code is calling Me.Close.
I suspect it has something to do with background .net threads or something, but I have no clue how to deal with those kinds of issues. How can I stop the program as quickly as possible? If code after my Catch executes, it will (and does) throw lots of uncaught exceptions later. Currently, it is not feasible for me to try to catch all the other exceptions. I just want to report an error and end the program.In my form load routine, I create and set up a number of objects and arrays by calling various subroutines.The success of most of the subroutines depends on the sucess of three subs in particular, which are called early on. If one of those three fails, there will undoubtedly be a number of hard to trap exceptions later on in the load routine.

I made button 4 on my form. When I run the program I find that it disappears.
I look at the visable property and I see that it is true. So what might be the problem. I also have button one that I put a message box it. When I hit the button durring run mode it will not activate. Have I missed up something here?
I copied a project I wrote on my XP machine to my other computer with Windows 7 64-bit. When I run it through VS2008 it exits immediately. It does not run a single line of code. The exit code is 0. I need to post what else it says. But I did find a posting about this saying the path to the temp files may be wrong for it but he did not know how to change this. If I create a new peoject and put a command button on it, the program runs. So I was wondering if it is something like the temp files or something else. The machine runs a compiled .exe of the program from the XP machone when installed on the Windows 7 machine. So I do not think it is the program not being compatible.
View 5 RepliesAll of a sudden a bindingnavigator that I use has started disappeared when I run the program. It disappears in the design view too, but if I click its name down below (where all the datasets and bindingsources go) it comes back. Then once I run again it doesn't show up. I know it's still technically there because no errors in code occur, but why is it doing this?
View 2 RepliesI have a VB program that displays a PDF file. When the program is closed it takes 30 seconds or so before AcroRd32 process releases the PDF file. In certain circumstances if the program is restarted with in this period, the PDF file does not display. The specific circumstances is that I have a second program (re)starting the program that displays the PDF file.
a) Make the PDF file be immediately released when my program closes
b) When the PDF file is loaded test that it properly loaded so that it can be reloaded if necessary.
I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?
Here's a couple of videos of the problem:

Notice the black screen with the white lines on it or the flash of the desktop after I click "Movies." How do I get rid of that?
Can I make a certian function that will fade out [make a black screen that fades out for 2 seconds], then come back? Is that possible? ON A FORM.
View 3 RepliesI'm not positive if this should be here or in graphics so I'm sorry if I'm posting it in the wrong section.I'm trying to make a program for the game Go. Now before getting upset that I want to make the game go I just want to say that I have looked for months for this specific thing and I still have yet to find it. I want to make something to simulate go so that two people can play on the same computer. The problem I ran into was capturing stones. Stones are captured when surrounded and then they are taken from the board. The problem is that I don't know how to make the program know when a black stone is surrounded.
I have thought of a grid detecting but the possibilites on a 19x19 area are too high for anybody to sit down and program. I have also thought of using picture boxes and the edges to detect other pictures, but there are ways for stones to group together and the opponent must surround all stones to capture them.
I wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

I have a VS 2008 Solution in VB.Net that has 2 projects - a Launcher and the App. The Launcher is what runs first, checks to make sure the App has all the latest files from the network, etc. and then launches the App. The Launcher allows the user to select their environment (Test, Production) then passes those values into the App.exe as command line arguments.
This works fine when running normally, but when trying to debug this, I'm trying to figure out how to start Debugging from the Launcher, then pass the selected Environment into the other project so it can read them as command line arguments.

When i debug the program and open it(inapp.exe) in notepad there a line
C:UsersendroitDocumentsVisual Studio 2008ProjectsDataTypeDataTypeobjDebugDataType.pdb
Well, is there any solution or way not to include that line when debug. I know that .pdb is important in debugging, but when the app published still there's that line. Can we disable it or there's no other way.
