I am using mssql 2005 and vb.net 2008.On my tblstudent, I have a field named "StudentID" the datatype is varchar(50), my format is "0001","0002","0003", and so on..what i want is, every time I click my btnAdd (to add a new record), i want the format will also be like that, but even I typed "0004", it will be saved as "4",I tried this
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click isAdd = False Me.StudentIDTextBox = Format(Val(ds.Tables("ADO_PRACTICE").Rows(inc).Item(0) + 1,"000#") but it doesn't working.
i have just switched to VS 2008 from 2005. On every web page I create, CSS styles are being automatically generated and added to every control on the page ... this is driving me crazy. Is my setup wrong? And, more importantly, how do I stop this very annoying event?

I built the sample project "How Do I" Data Access and ran into a problem adding, updating or deleting records. The project works like a champ until this step... It will let me delete, change or add records just fine, but when I save and close project and go back to my "show table data" in the database explorer nothing has changed?
See the code below which is triggered on a datagridview row validation event where the datagridview datasource is a datatable.
The messagebox shows that it loops around as expected populating the datarow with the expected values (NOTE: There are no primary keys as this is a college assignment with specific requirement and all fields can be nullable).
I had to use ImportRows as AddRows would always error due to "This row belongs to another table" the odd thing was the values were different and again the table contains no primary keys.
The code below runs but never adds a datarow to the dataset datatable "Bookings", does anyone know what the problem might be?

I am working on a MDI form application. I have got a menustrip control and some toolstrips. I want to add a button to the menustrip, to close active document.

I've added a COM reference to one of my projects (the DLL resides in C:Program FilesIntwerwovenWorksiteiManage.dll) but when I view the References in my project the path is something like c:usersusernamedocumentsvisual studio 2008project nameobjdebugiManage.dll..I seem unable to edit this path. I can remove the reference and re-add it using the browse button, picking up the correct dll but it keeps showing as the path of the project.The application works on my development machine but as soon as it's deployed to a client machine it complains of the missing DLL. Of course, the DLL is present but the app is looking in the debug folder.

I need to make a custom control and decided, before that, to see if there were any additional components that I could utilize.When looking through the list, I found a component called an Expander. So I decided to add it and see how it works.
After adding it, I couldn't find it at all within the toolbox. I went back to Choose Items and it was checked, but still not in the toolbox.It's probably important to note that it is a WPF component and this is not a WPF Project. Would that make a difference?Is there something else I may be doing wrong?
I know you are going to lough about this , but I guess I deserve it ...I am sure I am doing something wrong , but I can't find it out ...I have created a collection , lets sayMyCollectionI have also created a class , lets call itMyClass
Today I'm facing the problem of adding code when the program is running.I know i can execute command, (like when i press button1 it does the command in textbox1) but I want the code to be saved.Using the setting or resource tab is not an option, (don't ask why).
