Not sure i understand the question, but perhaps you could make the first row of cells to be labels with the headings of your columns as their text. Maybe make the text bold and background different color to distinguish them from the rest of the datarows?

The .net datagrid control is total garbage!
Every one wants to sell you a datagrid control that doesn't really do what you want it to!
Can someone please point me to a free datagrid control that has an event that will tell me which row or item a user clicks on.
Please Please Please!
Thanx in advance!

how can we implement different file formats in VB.Net
divya
|
|
|
|
|
By writing code that handles different file formats.
I think you are going to have to be a bit more specific if you want a better answer than the flippant response I gave above.
|
|
|
|
|
First explore yourself in MSDN; how many file formats are available in VB.NET. Which 1 u want?
I think self learning and understanding may increase your knowledge-base.

I know that - but shouldn't you be telling the OP that?

Actually i want to make an application in VB.Net through which we can upload different file formats just as rtf files and more type of files and after uploading we are able to see that files

Still too vague. Specify each file type you are interested in.
With RTF you have the option of a RichTextBox (If your application is a windows forms application) in order to show the file. If not then you are going to have to obtain the specification of RTF and provide your own means of translating the file into a viewable format.

I'm trying to populate a checkbox on a grid. The sub calls the procedure and populates the datagrid without error. However the checkbox does not populate with the correct values and each line shows a "checked" check box
Can you let me know how I can convert the 1 or 0 that the procedure is returning to display a check or blank in the checkbox? An outline of the code is below.
many thanks

Why can't you compile and check it yourself?

Hi
I have a combobox binded to a table in database.
Table is JobMaster in that there are 2 fields 1)JobCode 2)JobName
In the Combobox I show JobName as Display member and JobCode as Value Member.
When i make a new entry its easy to select the Jobname and JobCode is returned as selectedvalue.
But for editing i have the jobcode from the query, and i have to select the corresponding jobname...how can this be done?
Please Help

Make inner join to JobMaster table/query in your query.

Nope, that won't work. What you want is to make use of the HtmlTextWriter class. Find out more about it here[^]
Hope that helps.

Hi all,
I was wondering the other day how I could edit a standard toolstrip and have the change reflected globally (on any project). Looks like I succeeded... but I don't know how I did it ! OK, OK, lets say I am weird.
It is the DataNavigator I changed something in. The record count right part is of {0}. I am using VB Express 2005 English, but I live in Québec where we speek French. Some time ago, i changed of to be de. Today I realized that whatever program is running, it always shows de instead of of. Nice to me. But the thing is I don't know how I did it 
I must add that when one looks at the form in the Formx.[Design] window, it shows of {0}, and it shows the same in properties (Text). If I change the text property to say sur {0}, the program displays sur total, and if I then change it bakc to of {0}, the it reverts to displaying de total. 
Can someone help ?
Thanks

I stand under correction but it may be from the .resx resource file attached to your app. I assume that you have your regional settings set up for french-canadian and that your app has somehow picked up on that (you haven't done any localization/globalization to the app?).
Again, I say that I stand under correction and may be completely wrong.

True, my regional settings are set up for french-canadian. What bugs me is that every application is showing de instead of of, even those I downloaded from Mircosoft WEB Site yesterday.
I have not done anything in term of localization. My goal is to localize everything about the DataNavigator toolstrip (for example tooltips). If I can do it once for every application, then it's fine. For sure I have modified something somewhere, and it is spreading out. Just can't find where.

Hello
I'm working on a small application that uses an MS Access 2003 database with one table (tblEvents). In one section of the application, the user will fill out several fields and then click the "Submit" button. Within my Click event handler for btnSubmit, I use the following SQL query as my command text:
Dim MySQL As String = "INSERT INTO Guestbook " & _<br />
"(Planner, Location, Time, Date) VALUES " & _<br />
"('" & txtHistoryPlanner.Text & "','" & txtHistoryLocation.Text & "','" _<br />
& txtHistoryTime.Text & "','" & txtHistoryDate.Text & "')"
I took that string directly from a tutorial on the web strictly about updated rows and querying for rows out of a 2003 Access database and I'm 100% flustered because my app gives me an error stating that there is a syntax error with my INSERT INTO query.
If you know what's going on, please enlighten me! Thank you for your time.
