I've got a WPF application (the WPF part shouldn't make a difference i don't believe).
It loads fine, however whenever I click into a textbox it crashes.
What could be the problem? how can I troubleshoot this?
im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

View 4 RepliesWe have a client who has asked us to write a GUI that is capable of connecting to an existing, running application. This specific application has quite extensive .NET and ActiveX hooks in it, but it's a third-party application and we do not have access to the source code. The client has specified VB 2008, despite the fact that the target application has perfectly good GUI creation tools itself.
I can successfully start a separate instance of the target application, but that is not what the client wants. The idea is that the user would start this application, open a specific file with it and then start the GUI which would take control.
I have searched a number of locations (including 18 pages so far of this forum) to try to find help on this sort of thing, but the success is slow coming. One code snippet enabled me to find the running process, which may help me to connect. I am also browsing CodeProject to try to wind useful information on this.

View 1 RepliesI am trying to manipulate files as part of a Document Management application that stores documents in a location on a Network Drives. But the My.Computer.FileSystem.Drives collection does not contain the Network Drives mapped on my machine. I have about half-a-dozen of these, but none of them seem to show up in the Drives collection and thus are not visible to the other FileSystem functionality I need to use for file management.
how to make sure the Drives collection contains all my drives? I am running VS2010 Premium edition on Windows 7 64-bit on a 64-bit Dell machine.
I was studying visual basic 2008 and had reached almost 60% of it when I was told that my course curriculum included visual basic 2005. I will now have to reinstall visual basic 2005(.net framework 2) instead of visual basic 2008(3.5 .net framework). I was wondering- will it be completely different vb2005 and vb2008? I really wanted to stick to vb2008, I was getting the hang of it. Also, I was wondering, can I run my application vb2008 in .net framework? Is there any way around? Also, I used advanced installer to build a setup file for my application? Now the question is will the other computer(the one which will install from the set up) need .net framework of 3.5(since I built apps in vb2008)?

is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?

View 3 RepliesI am making a exe application and i am using mysql as my database. So the thing is, when i change to a new computer, i need to change the file path for the database connection string to that computer.
like below:
Dim connectionString As String = "Data Source=----------SQLEXPRESS;Initial Catalog=Flexlink;" & "Integrated Security=SSPI;"
i need to change the data source = --------------- SQLEXPRESS to the computer name that i am using for my project.
May i ask is there any method such that the user dont have to go in to the source code to change the computer's name like those normal installer?
Just install and the application will run according like any exe file that we buy.
