I am converting old VB6 code to VB.NET with ADO.NET (OleDB). This is my query that will create a blank table when ran in VB.NET, but then works when ran directly in Access. This code presumably also works in VB6, as I am using the same SQL:
SELECT qryAsOf.name, qryAsOf.type, 0 as opt, 0 as swap
INTO qryCon
FROM qryAsOf
LEFT JOIN qryLinked on qryAsOf.c = qryLinked.lc
I feel like this has something to do with the left join and select into being together, but like I said it is only VB that has an issue with it, Access handles it perfectly.Without the INTO line, this query returns all 600+ rows.
This DOES NOT WORK:
cm.CommandText = "CREATE TABLE qryCon (etc...)"
cm.ExecuteNonQuery()
cm.CommandText = "INSERT INTO qryCon SELECT ..." '(rest of query above without INTO line)
cm.ExecuteNonQuery
This DOES WORK:
cm.CommandText = "CREATE PROC qryCon AS SELECT ..." '(same select as above without INTO, again)
cm.ExecuteNonQuery
The CREATE PROC that does work is fine, except I need to insert data into it later, so I get errors about how I need an updatable table. I really want the end qryCon to be a table, but I can't seem to get that to work :(
*However, when I do something like this (using the stored proc (renamed) above which, if viewed in Access, is full of data)
cm.CommandText = "SELECT * FROM storedProc"
dr = cm.ExecuteReader
[code]....
This DOES NOT WORK! By the way, I removed the concatenation in the query for readability. It is correct in the actual project.

I am trying to export data from a datagridview which works fine, but it crashes when pat_eid value is empty, as pat_eid has been set a primary key and cant accept null values in the database level.
So, I want to enter a message box if column(0) which is the pat_eid has an empty field. Please could you advise me how to do that.

Problem: 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.

I 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.

The code works fine when I run it locally, yet as soon as I have uploaded to our dev server it doesnt run, but also doesnt error.I did some research and found that I should have the thread impersonate the WindowsIdentity, which I have done but still the thread does not work, I also tried increasing the max threads in IIS and still nothing.Im running IIS 7.5 on Windows 2008 R2.The method being executed on a new thread is in a class in the App_Code folder and looks like:

I 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...

I 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?

Here's the code that I have:
TextBox3.Text = ""
WebBrowser1.Document.ExecCommand("Copy", False, vbNull)
TextBox3.Paste()
TextBox1.Text += TextBox3.Text & vbCrLf & vbCrLf 'This code just adds the pasted text from one textbox to another.
Question:
After I install and run the application on my main computer that I coded this app in work, but when I go to transfer/install it onto my laptop, the code will NOT copy and paste from my webbrowser to my textbox?

We 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.

I 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.

So 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.

[code] BUT, in code, watching the locals window for rec.EOF and rec.BOF both return true and therefore no results.Why does this work in VB Query Designer but not in code? If I remove the WHERE statement than the results return fine as expected.But its returning ALL of the results which is no good.

I am running a simple test app that opens an OLEDB connection, retrieves a single value, then closes. The compiled (console) app works fine, but running it from the IDE causes either a silent close (if it's a winforms app) or a crash of vshost32.exe if it's a console app.
The devenv is VB 2010 Express on Windows x64, but I have the configuration manager on the solution set to "Debug" - "x86".

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

using VS2008, targetting framework 3.5I have a rather complex UserConrol which does some of its own rendering.I display this UserControl on a form.Opening that form in the Designer creates an instance of the UserControl in the Designer, which tells me a NullReferenceException is occurring in one of my rendering methods.I have attempted to correct this by making alterations to the UserControl's default constructor, but have not found success.

I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,
