Visual Studio Datasource - Error "There Is No Row At Position 0"
Feb 19, 2012
have another problem in visual studio(winforms). I have sql server r2 as my database .
[Code]....
Everytime i input a value in the textbox1 then it shows on name and address. when the value inputted on textbox is invalid. It shows me this error "There is no row at position 0". Yes, because the value is not on my database. How do i make a msgbox that prompt whenever the user put an invalid or not on my database values?

Ok, so I've got this Visual Studio 2008 Project I was working with about a year ago perhaps. And this project had a datagrid that was linked to an external database running on a server off the internet. Now, this databinding was all done using Visual Studio 2008's built in features. But how can I now change the binding to a different server, without destroying the project? I've noticed that a lot of the code that Visual Studio creates makes a mess. So manually trying to change the datasource has allways f*cked up the whole project for me.
I'm not all that good with this stuff, that's why I used the built in features of Visual Studio. But I noticed that several things appear, like a binding source, and a dataset. Is it possible to do this? Perhaps even better, making these settings be controlled after the program has been compiled. The way it is now, it's all hard coded after compiling, and that kinda sucks. I remember trying to do this about a year ago, trying to bind these settings to variables stored in settings. But I never got that to work. Just throwing around ideas here

I have a simple question, in the IDE of the vb6, when we make right click, anywhere in the code, we have some options like Definition, Last position etc...in visual studio .net, I can find in the context menu, the "Definition", but can't find go back to "last position", does it exist ?If yes, how to activate it or where is it exactly ? Also in vb6 we can do it using the shortcut Ctrl+Shift+F2 I tried this shortcut works on vs2008, but why can't we find it in context menu ?

This is my first try of Visual Basic 2010 Express, though I have 10 yrs+ experience in VBA. I'm running Windows XP SP2 on a desktop pc with following installed: Visual Basic 2010 Express... just installed! SQL Server 205 Express ... been running on pc for 12 months I've created a new DB in SQL for my test application, but have not added any users or permissions to it as I'm using Windows authentication.
I've created a new Windows Forms Solution in VB2010EXP and tried adding a new Data Source for my new SQL DB, but it keeps giving error message about not having rights ot the db. 2 days of searching on the web has confirmed many others with similar issues, but no obvious solution. Eventually I find a few threads about permissions and moving the mdf into the root of the HDD, so try moving my mdf file up closer to the root of the Hard Drive msf was in C:Documents and Settings\_SharedDataApplication_DataMSSQL2005Data now in C:SQL2005Data

I am programming in VB9 WPF and Blend 3. I was working on a program in Blend 3; I can work on all my forms and everything runs fine in Blend, but when I opened it in VS the WFP forms would not display (I have five of them in my program and they all have the same problem in Visual Studio.), but I can run the program in VS, see the forms in run mode, and work on the code behind with no problem. I can't determine what is causing the WPF forms error in VS. It appears I have a "ResourceDictionary_4 error, but I cannot locate that dictionary in either Visual Studio or Blend. I even tried searching my entire computer and can't find any trace of it. Are there any ideas as to how do I solve this problem? The error messages I am getting are:

I have a MouseEnter event which currently handles some custom controls on my form. The program is a card game. I have a collection (handCards) that gets populated when the user draws a card and then it adds the latest card to the form. This collection holds cards of various custom types, all which inherit from picturebox. Drawing the cards from the deck and adding them to the form works fine. The trouble I am having is that at runtime, after a card is drawn and added to the form, I've created an addhandler line of code to have those cards respond to my MouseEnter event, but my addhandler line of code is telling me that MouseEnter is not an event of object. How can I get around this so that after a card is drawn and added to the form, when the mouse enters the new custom control, my MouseEnter event fires? Here's one of the many things I've tried and what I think should be the simplest and easiest that should work.deck.DrawCard()AddHandler handCards(handCards.Count).MouseEnter, AddressOf Cards_MouseEnter
P.S. the MouseEnter event works fine for custom controls that are on the form prior to runtime and all it does is take the image of the control and enlarge it by placing the image to a bigger card on the form.

I installed the latest version of Toad yesterday. When I restarted Visual Studio 2008, the project that is my installation package for my application would not longer load. The message I get in the output window is "The Visual Basic Deploy Deployment Package ({CCD045E8-6236-4B3D-B820-97F7DD14C77C}) did not load because of previous errors." When I try to reload that project, I get the following error: " The operation could not be completed. No such interface supported" I tried to repair the VS installation, but that originally failed. The Deployment folder under Common7Tools was currupted so I ran check disk. A few bad files and clusters were found and corrected and the second run of check disk ran clean. I uninstalled Visual Studio and then reinstalled it, but am still getting the same error. I tried reinstalling .Net 3.5 before the reinstall of VS as well. I tried creating a new installation project, but that failed as well.

I have a large solution which contains a mixture of C# and VB.Net projects.If I get compilation errors because a project which several other projects depend upon fails to build, it is very hard to see the actual error(s) because of the number of VB errors in the error list window in Visual Studio. C# errors found in the projects I compiled show in the error list, but all VB errors appear (including in those projects I have not just compiled).Is there any way of turning off this behaviour so that VB errors only appear for projects that I have explicitly compiled?

Why does my VB.Net Project disappear instead of giving an error message?This only started happening recently, but when debugging with Visual Studios instead of getting errors, the program just closes as though the stop button was pressed. This doesn't happen for all error types but it consistently happens if there is some sort of casting error. This is an overly simplified example, but the lines below would cause a program to vanish as soon as they run. Dim i As Integer i = "A" One other interesting part of this is that if that was in a try catch block the error would be caught instead of closing the program.I'm in an office setting so I've been able to test a number of configurations and have found that this problem only affects Windows XP PCs, but not Windows 7. And it consistently happens with Visual Studios 2010 Professional and Ultimate, Visual Studios 2008. Besides that we apparently we all need Windows 7.

I have a class project that supplied me with an Access 2007 DB. When in VB and go through the steps for creating a data source. When the Wizard comes up I click on Database, Next, New Connection, Data Source is Microsoft Access Dagabase File (OLE DB), Browse to Database File Name, Test Connection is successful, click on OK, then Next. A MSVS box appears "The connection selected uses a local data file that is not in the current project. "Would you lie to copy the file to your project and modify the connection?"I am supposed to click NO. When I do I get this "Wizard Form" "An unexpected error has occurred. Error Message: Cound not load type." I need to be able to go to the next part of the Configuration Wizard that says "Choose Your Database Objects" I evensaved the file as Access 2003, and it will not work.
