Exe Closes System.IO.StreamReader Kills Program?
Apr 24, 2011Ok, So I am making a front-end for a program, and it runs the exe with command line arguments. One of those arguments is creating a log file that tells me who the winner is. Currently I have code that runs the app, tell VB when it exits and then does another event. When testing with message box as the other event, works fine.
When running the System.IO.Streamreader the app just closes down on its own and there are no errors shown.

View 5 RepliesRunning 32bit Compiled Program/DLL On 64bit Machine?
May 20, 2011I have some programs written in VB2010 using functions from a DLL. I have compiled and run these programs on a 32bit XP computer and a 32bit Win7 computer and have had no problems accessing the DLL.I have published an installation of these programs and tried running the install on a 64bit Win7 machine and the installation is performed correctly. It installs the programs and copies the required DLL into the same folder. the problem is that whenever I run the software and try to access the DLL I get errors.
The error says something like:
An unhandled exception has occurred in your application. An attempt was made to load a program with an incorrect format. (Exception from HRESULT:0x8007000B)
If I click past it the software runs and all of the forms are loaded properly, but anytime in the software if I try to access the DLL I get the same error.I am declaring functions in the DLL like this:
Public Declare Function OpenDriver Lib "OP815M.DLL" (ByVal handle_Renamed As Integer) As Integer
I have also tried placing the DLL in the system32 directory and also the sysWOW64 directory and that did not help as well.I do recall that hardware drivers need to be properly signed and pass the Microsoft Logo testing. Must I get the DLLs I am using properly signed?
Edit: Also it might be fair to mention that I have used the DLL with another program written in C, which would run in the DOS command line in Windows and it correctly accesses the DLL on a 64bit machine, but just when run from the DOS command line in windows.
VB2005 32bit Program NOT Running On 64bit Systems
Oct 16, 2009I developed a Visual Basic program in VS2005 that uses SQL2005 on a 32bit system, which runs perfectly on 32bit systems using Click Once deployment, but whenever I try to load or run same program on any 64bit system, it does not load or run. What do I need to do to make the program run on 64bit systems.

VS 2008 Running A Program Built For AnyCPU That Is Only 32bit Compatible On 64bit OS?
Jun 14, 2010Basically i want to run a program that is created in vb2008 with its compiler properties set to AnyCPUThe programmer has a 32bit os, so he has not recognized that his referenced assemblies are not compatible with 64bit OS and therefore throw system.badimageformatexception on 64bit OS (such as mine; im running windows 7)
now it is my understanding that all 32bit applications can be run on 64bit windows because the WOW64 emulator can run them (just like programs that get installed in the program files x86 directory)so the problem here is that my OS cant recognize that this program must be run in 32bit since that programmer foolishly set the compile options to anycpu i can not contact the programmer and therefore asking him to recompile is not a possible solution.So, how do i run this program as 32 bit on my 64bit OS? how can i manually set 32-bit compatibility? it is not available in compatibility options.I tried running in compatibility mode for windows xp sp2 i tried putting the software in program files x86 folder.
IDE :: VS2008 - ComboBox Kills Form When Debugging?
Jan 26, 2010I just moved from VS2005 to 2008. All seemed fine until I started playing with locally cached data sources. After that I started getting this problem and now I get it even when starting a new project. I start a new project and debug, Form1 shows and all is well. If I add a combobox to the form and debug the form immediately closes. It doesn't seem to do it for other controls.

View 11 RepliesWhy Will This Run In 32bit, But Not 64bit
Jan 18, 2010I'm using the following code to iterate through and find windows containing specific strings in their title bars. I have two projects containing this identical information, yet for some reason - it works when targeted to x64, but FindWindowLike returns 0 always on x86. I need this to run in x86.I am developing this on Windows 7 x64, but it needs to run on my machine as well as XPx32. What I can't fathom is why it compiles/runs on x64 but not x32 (considering I'm targetting user*32*.dll)

Oct 14, 2010Depending on what component is handling the print for you, some of them are not 64 bit ready (i.e. 32 bit only). To use them you must compile your application as 32 bit only. It will then run on the WOW platform that Win7 supplies.
You change this option on the PropertiesCompile screen. Press Advanced Compile Options and review Target CPU:
IDE :: Debug Not Working In 64bit?
Oct 12, 2011I've downloaded the 64bit debug symbols and told the IDE where they were located. But for some reason, VS won't build a 64bit debug EXE.
This is my first time doing 64bit so I never had to worry about it before. Is there something I need to do in the IDE that I don't know about? I went to Project Properties and set things to 64bit debug. But when I compile the program, it makes a 32bit program.

Jan 4, 2010I have a .net Application that writes text to a serial COM port, a POS reciept printer to be more exact. i am using the Rs232 class library to write and read to a serial device.My problem is now with some clients that have updated their operatingsystem to WIN7 64bit version, have trouble to create a connection to the COM-port. the com-port seemes to get occupied with some other process and that blocks my application to opening a new connection. so for my question, does anyone know how i can close all connections to a com port? or see whats blocking it? once again this seems to only to affect win7 and 64bit users.
