VS 2008 SQL Constraint Exception - Works Fine In Query Builder
May 3, 2011I have created a query method for my tableAdapter in the dataset designer. I typed the command text manually, but tested it in the query builder after I got a Constraint Exception when debugging. When running in the query builder via 'Execute Query' I get exactly the results I expect. When running the application I get this exception: "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I tried temporarily setting my dataset's EnforceConstraints property to FALSE but still get the same exception. I can't understand why the Query Builder would return the correct datatable but running the app would not. Is this a bug?

VB Program Works Fine When Stepping Through But Crashes When Ran With The .exe?
Aug 12, 2011Problem: The excutable of the vb program crashes when trying to run but when I step through the program inside of visual studio it runs successfully.
Details: The program performs a winscp.com transfer from a ftp server and then takes the downloaded file and extracts the data from it before sending it to a webpage. The program also decrypts a des3 encrypted file which holds the login details for the sftp server and the webpage.
My Thoughts: I was thinking this could be something to do with the excutable jumping ahead of the slower transfer and decrypt functions thus causing a "file not found" exception to be produced and the program to exit. Lending to this if I slowly (aka spend 10+ seconds stepping through the code) move through the code it works just fine.
As requested Crash Messages:(I capture everything in exceptions and exit properly so no "crash" is reported but the error I get in my logs is as follows:)
1st run with standard test case:Could not find file 'C:UsersAdministratorDesktop..ILC2INFOENC.txt'
2nd run standard case (the file above was not deleted by my cleanup function either as it could not be found)Could not find file 'C:UsersAdministratorDesktop..ILCNETSL10663.csv'
Background:The first file that is found missing is the encrypted login information file while the second file is the winscp.com downloaded csv file.
.Net Application Stopped Working On XP But Works Fine On Windows 7?
Jun 23, 2010I have VB.Net application that has worked fine for years on XP and Windows 7. For some reason the last update I put out does not run even the simplest VB commands.Simple Environ() fails.I have tried putting simple VB commands onto a MsgBox on the start of the app and everything raises an error. I have no idea what is going on! The exact same app runs fine on Windows 7 clients. All the XP machines including a fresh XP virtual machine with the .Net 3.5 framework even gives the errors. No VB commands are working. I thought maybe something happened to my vbproj files, so I copied an older one from a couple weeks ago when things worked fine and it still does not work.

View 2 RepliesCustom Scrollbar ... Works Fine Until Move / Resize It In Designer
Oct 28, 2011I have been scouring for examples to give me some idea on what I need to do to create a skinable scrollbar. The only thing close that seems to work like I need is Cool Scrollbar The problem I am running into is on the designer...when I move it, resize it, or change the direction of the control (ScrollbarLayout), it seems to want to re-name the class the item is an object of from CBar to cbar.CBar. Once I position and align it properly to check, I can go through the Form1.Designer and simply remove the cbar. and get no errors. When I run the program, it is fine, so this is telling me that there is something wrong with the movement in the class...

.net - Out Of Process COM Server Works Fine In The Unit Test Harness But Not In The Real Service?
Jun 1, 2011We have a WCF service hosted in IIS that currently calls a VB6 DLL to do part of its job. This works fine, but we can't deploy the service to a 64-bit target environment without configuring IIS to run it in a 32-bit worker process.I am currently investigating ways around that restriction. Porting the VB6 DLL to .NET is not possible for various reasons, so I created an ActiveX EXE wrapper around the DLL in VB6, so that the service can run in 64-bit and the VB6 parts in 32-bit.
When I tested the service I got this error:
Type: System.UnauthorizedAccessException
Message: Retrieving the COM class factory for component with CLSID {9AE7303B-D159-43F6-B1A5-52D297581820} failed due to the following error: 80070005.
After some Googling I found that this is due to either:
Calling an MS Office component
DCOM permissions not being configured
NTFS file permissions not allowing read/exec access to the IIS worker process identity (ASPNET in my environment)
Of these:
Definitely not applicable Also not applicable; I am not hosting the EXE in DCOM or COM+, just a simple COM out-of-process activation
This looks likely; however, I checked the permissions, and NTFS reports that the Users group (which ASPNET is a member of) does indeed have read/exec access to the file I tried calling the EXE from a unit test fixture, which is executed in my admin-level account rather than the IIS worker process account, and it worked fine, so the error is definitely something to do with permissions. I'm not sure what to do next.
UPDATE:The IIS virtual directory is configured for Anonymous+Windows access; the WCF service uses only Anonymous authentication, the Windows authentication is for the VS debugger. Task Manager reports that the aspnet_wp.exe process is definitely running in the ASPNET account.I explicitly granted Read and Execute access to the ASPNET and IUSR_<machine> accounts on all the COM exes and dlls involved. This made no difference.
I explicitly granted Local Launch and Local Activation access to the ASPNET and IUSR_<machine> accounts on the relevant interfaces in the DCOM configuration. This made no difference either.Keep trying to get this working somehow.Go the whole hog and host the EXE in COM+.Give up. Tell users that the WCF service must be configured to run in a 32-bit app pool on 64-bit Windows.

Visual Studio 2010 Created Program Doesn't Work On Windows7 64 Bit While Works Fine On Windows Xp
May 15, 2012I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

Multiple Runtime Exceptions When Clicking Run From Task Scheduler / Works Fine Running Application From Project Folder
Jun 3, 2011So I wrote a VB.net project in Visual studio.I have a scheduled task that is set to run the program every morning at 10AM. If I use windows explorer and double click the application, it runs fine.If I open task scheduler, open the task properties, and browse to the application, then choose run, the program fails, due to Runtime exceptions.I know I have the path entered correctly, since I can debug the instance when it crashes from the task scheduler. VS2010 pulls up my source code.The exception is System.IO.FileNotFoundException, remember, it works fine when I double click the app. If attach a debugger to the process after it is executed from the task scheduler, I can then restart the debugger, and Voila!, The application runs fine.

Adding Additional Lines To Multi-line Text Box?
Apr 6, 2012I have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import. So I have a display of mulitiple lines, showing multiple Imports.So this is one I have for the first section, it loops through the data so you see the rows incrementing
TextBox1.Text = clsDatRow.iFirstVal.ToString + " ROWS:" + iCountRows.ToString + " " + Date.Now.ToString
TextBox1.Refresh()
Now, I can I keep the line of data, and add a new line so for the next import, it does the same thing. It ried vbnewline, but it just clears that line, it doesn't move down to a next line.

It would make sense if I had Throw ex, but I don't. Isn't Throw by itself just supposed to rethrow and bubble up the error?
