I have a checkbox column in a datagridview.
I only want the user to be able to select one item in the datagridview.
But i don't know where to begin to get a count upon the number of checkboxes that are checked
Any help is much appreciated.

What is the DataGridView bound to?
I mean, is it a database, a generic list a non-generic list.......

It is bound to a datatable populated by a database stored proc

The only thing I can think of that might work.
Have a int field to track the row index of the 'true' row call it trueRow for illustration.
In either the OnCellClick or OnCellLeave handler, compare the row (e.RowIndex) to trueRow, if the same, return. If not the same, test if the cell (e.CellIndex) is the CheckBoxCell and if so, set the checkboxCell value from trueRow to false, store new row in trueRow.
Sorry not to be of more help.
Good luck!

I am completely new to vb 6.0. I have sstab control in which i have 4 tabs
GSM,GPRS,CDMA,PSTN. Each tab contains should contain a set of controls. The problem starts there. I am not able to put controls in the tabs so that the controls are visible only when the corresponding tab is clicked.
Thanks in advance

Abandon vb6 and do it in .NET
Seriously why do people still program new programs in that language.
It never was any good, the language is dead and has been for several years and its no longer supported.

Tom's right, Get VB.Net, it is a free download.
It (VB6) is unsupported and opens you to ridicule and shame!

Great! Stop while you still can and be completely new to VB.NET before VB6 teaches you a ton of bad habits you have to unlearn to move up to VB.NET!

But the current project is in vb6 and we have an urgent demo. So there is only one option(continue working on this till the demo is complete).So if any one knows the solution kindly let me know
Thanks in advance

I couldn't tell you - I haven't used VB6 in 8 years.
I'll warn you now - VB6 has been unsupported by Microsoft for quite a long time now, and its runtime will not be supported under Windows Seven. Your app will work under XP, may or may not work under Vista, and won't work at all under Windows Seven.

Hi,
I am not shure, but in VB 6 you have two Tab-controls (I do not remember witch is witch). There is one, that only shows you a tabbed layout on top, and not hide any controls, it you click a tab. Then it has one (in a external ocx, I think) that does what it is supposed to do. Hope this helps.
By the way, it is a good idea to change to VB.NET, you need to have some time to learn it properly, but it's worth it.
Regards: Didi

OK..Thank you for reply
And iam sorry for the bad writing in English because I speak Arabic.

You language is not a problem, many here do not have English as first tongue, but never ask for code, write some code, then if there is a problem copy it here and ask for help, many people will be pleased to help or offer advice.
They might even RE-WRITE part of the code for you, but they will not just give it to you for nothing.
They need to see you have done some work.

Try changing
For fileCount As Integer = 0 To theFiles.Length() - 1
to
For fileCount As Integer = 0 To theFiles.GetUpperBound(0)
I'm assuming the error is an index out of bounds one.
If not, what is the error?

Then either the input line is not as expected (e.g. blank line somewhere in the file) or p(1) has not been set correctly.
I suggest setting a breakpoint on the line, pressing f5 and looking at the values of s and p(1) in the locals window.
That should tell you which it is.
I did have a problem in GetColumnPostions because of the accent in "Nom du Modèle" not matching the text in a test file - it set p(1) to -1.

hi ,
i am new to this programming world...
i have been asked to create a simple VB application which uses a COM application written in vc++..
For eg., addition program..
VB gets two input. COM processes them and returns the answer to the VB and VB displays the answer.
does anyone know how to write code for that?? some tutorials or sample applications will be more helpful.

You have to create an instance of the COM class in your code, then you can call the methods and properties of the object. Add a reference to the COM library, under My Project, References tab.
Then you import the namespace at the top of your code. Once you have that, it's as easy as creating any other object:
Dim s As New MyComObject

Hello all:
I am hoping someone might be able to shed some light on this!
I wanted to pass the following string as a sql query in VB6 (it is not by choice I am doing this in vb6, it is an old app)
sql = "Select enteredvalue from Eln_property_values where property_key = 2381 and section_key IN (select primary_key from eln_sections where Name = 'Version Overview Page' and section_set_key IN (select Target_key from eln_references where Collection_key = 25))"
the strange thing is when the string is created it becomes: (the issue is at the end)
sql = "Select enteredvalue from Eln_property_values where property_key = 2381 and section_key IN (select primary_key from eln_sections where Name = 'Version Overview Page' and section_set_key IN (select Target_key from eln_references where Collection_key = "
It seems to drop the value and the two parentheses. Strange??
Even stranger is if I replace "...Collection_key=25))" with ...Collection_key XYZ))" it becomes ...Collection_key XYy". I have no idea what is happening (I do not have alot of experience with VB6).
I am pretty sure I could break up the nested sql and run each select separately, but that does not seem like a great fix as there will be some unnecessary code and three recordsets opening and closing. Any help or thoughts would be most welcome,
Thank you
