I am developing a simple application in VB10 that uses ADO.net to store data in an Access database, and gets input via a serial port RS232. It works well, but is not fully debugged. Unfortunately, a problem has recently started where as soon as i close the program I get a blue screen. Makes it hard to debug. The solution does not even have to have run; it just has to have been loaded and then exit VB10. The blue screen aslo happens to most of the other example solutions that I have downloaded.
Questions:
1)How do you capture the STOP error codes (probably stupid question)?
2) Is there an easy solution that rings a bell? My IT support is trying but not getting anywhere. Have to believe it is hardware related, but the hard drive checks out with testing.
I have a vb.net 2.0 winforms application. When I open another application (like calculator) have the focus to it and try to close my application the screen freeze and I have to use ctrl + alt + del to get it to refresh.
When 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.
Using this code, before I added the funky "abort" button code - stopping it using the Stop Debugging button in the IDE blue screened my computer every time, PROCESS_HAS_LOCKED_PAGES - Anyone care to try it ? Win7 Ultimate , VS2010 SP1. This machine has never blue screened since it was built. Code is by no means exotic in any way.
Public Class Form1 Dim Abort As Boolean = False Private BStart As New Button
I was attempting to clean up my serial port example that is in the code bank. I had decided to use a modem, thinking that a lot of computers still had them. By using the loopback feature of the modem I am able to simulate / emulate various features of the serial port.All was going well, and then I got a Blue Screen with this error after running for 10 minutes or so:DRIVER_IRQL_NOT_LESS_OR_EQUALSTOP 0x000000d1 etc.I then went back to using my GPS receiver, which sends messages constantly to a serial port. This test ran for several hours(4). It received messages correctly during the entire test.I then created a new, not as complex, version and it also receives the Blue Screen. I have made sure that the modem drivers are up to date, searched for the error, etc. My gut is telling me that it is the modem driver. I have attached the project. This is the scaled back version, but it uses the same functionality.
I was trying to install a program and it install fine but when i went to run i clicked the icon and i got a blue screen and it rebooted, i found out from the program site that its caused by framework.net, i need to update mine, or fix it i check my add or remove programs and i had 2.0 i went to get 3.0 and it told me that cound not cause of prev version was not upto date.
Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?
I have a vb application its a point of sale system and its running on 4 computers at 2 different locations ever since i upgraded those 2 sites from the old vb6 to our new vb.net software they keep getting blue screen randomly. [Code] Both location have the same exact setup, ie video monitors ram and so on. I have installed every update there is including updating the BIO.
I added an splash screen to my app. Then in the project settings I selected it to be used for the splash screen. Now my app won't close when I try to exit my app. I have 'When Last Form Closes' selected for the shutdown mode. So I'm guessing the splash screen is calling Hide() instead of Close(). I can't find a way to get access to the splash screen object so I can try callling Close().
I have a project (Written in Visual Basic, using Visual Studio 2005) which has several user controls. I have had no problem setting it up where you click a button and it load a user control, but I cannot get it to remove the control that is currently open. For example The program opens on a starts screen, which has the choices, Control1, Control2, and exit. When you click Control1 button it should open up a screen to display an inventory. It does this just fine, but it does not close the main menu screen.
Here is the code for the initial startup of the project: Public Class Form4 Public Sub Form4Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim CtrlMain As New ControlMain() With CtrlMain .Location = New Point(0, 0 [Code] .....
im about to develop a small appliacation for a bet system, which needs 6 screens, each screen will be a touch screen for each client... the application will be running in one computer only just with 6 screens. my question is does anyone knows how to control each screen separately?. somethign that would allow me to output each forms in different screens would work fine.
I have a alpha mask (grayscale)... and want to specify a color (eg color.blue) and then be able to paint the blue version of the new image(using the solid color with the alpha mask) to the screen using graphics...
I am making a program that will put a black mask over an application (like a full screened game). This black mask will fade in and out, depending on certain criteria. Is there a way I can do that with VB? It's to help me dim my monitor without having to push anything.
I'm having a problem over here; I'm developing a DirectX 9 application, and for some reason, I can't figure the way to close the application completely. This has never happened to me, to be honest. I am using Application.Exit(), which doesn't seem to do anything - it just closes the form, but the program is still running. I have also tried End, but it throws a run-time error I can't seem to figure out.
I have a form in a Pocket PC app that is set to be the Application form using:Application.Run(New frmMain())Somehow this form is getting closed for no reason while working on another form. No closing event is fired and nowhere in my code can you close the main form anyway. It is only closed by clicking the OK button at the top right of the window. When this is clicked, the user is prompted if he/she really wants to close the application. However, this is not occurring either.Basically, I am on another form which adds a new record to the database. After adding the record the gotFocus event is somehow called for frmMain. When the code in the gotFocus event reaches a reference to a control on the form, there is an exception that states that the object is disposed.
I'm getting really really frustrated with Word's Document Recovery Pane everytime I launch Word - it is making me very mad! I'm busy with a program which assists me with all my exams, right, now, with this program I'm launching each program associated with each exam. After the document / spreadsheet etc. is shown, I mark what I need to, then, I have a button which closes the current process, and returns me to my default application interface.
Is there a way to detect (an API call) when task manager is shutting down an application? I don't want the application to be shut down! How can I prevent that?
I'm busy with a program which assists me with all my exams, right, now, with this program I'm launching each program associated with each exam. After the document / spreadsheet etc. is shown, I mark what I need to, then, I have a button which closes the current process, and returns me to my default application interface. All this is working, except for the .doc files, Word files.
Everytime I launch word, I get the Document recovery pane.
I've tried the following: [Code]
As a last resort ( and this doesn't work ), because WordDocument.close does not work, Word Application. Quit does not work! By, saying it doesn't work, means it closes everything, yes, but the Document Recovery PAne always shows up, and I can't understand why! Is there some way of disabling it completely I know some will say it is not a good idea, I know, I know I really need to get rid of it.
How can I ensure an application is fully closed when the user selects the close window X at the top of the form. It appears to just close the current form by default which is leaving the program still loaded in memory when the user thinks they have closed it. I have tried capturing the close and running application.exit but this closes the whole application even when I only want the current form closed.
I just did some analysis by using a global function which is called GetCallingMethod in my case.
Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.
In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.
This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.
I keep receiving an "Access violation at address xxxxxx. Write of address xxxxxx." error when i close my MDI form (and hence my application).However this error only occurs after i have created a new child form.
I have stepped through the code and found that the exception is being thrown in the Settings.Designer file (Namespace My module). This is the chunk of code that throws the error[code]...
I've made a Windows Forms Application that runs fine. It has some buttons that open child forms, which can simply close again without any problem. As I need the form to be in a dll, I changed the application type to a class library and added an extra project containing an exe-file that only references the main form in the dll and shows it. So far so good...
The main form is basically a tabcontrol with a bunch of controls, buttons among others. Five buttons on different tabs use the same handler to open a child form. When I click the button on the first tab everything works fine. The form opens and when it closes, only the child closes. When I click any of the buttons on the other tabs, the child form opens and when it closes again, both the child and the main form close...
I am stumped, especially since all buttons use the same code to open the child form and everything appears to be completely identical, yet the results are not. Below I have pasted the code that opens the main and child forms. I am undoubtedly not looking in the right place, but I also have no idea where to look anymore, let alone what to look for...
The code opening the main form: Public Sub StartProgram() 'Load the form and show it Dim frmProgram As frmMain = New frmMain
