Thanks in advance.

I have a web form with 2 datagrids.
DataGrid1 has a few columns, the first of which is a button that, when clicked, causes DataGrid2 to be filled accordingly. The logic works fine.
Upon entry into the form, and immediately after filling DataGrid1, which will always have at least one row, I would like to "auto-click" the button in the first row.
How can I do this?
Bill

u mean when the from is loaded datagrid2 must b filled with the data that corresponds to the value of the first row of the datagrid1 right?
i am not sure but i think you can retrive the desired cell of the datagrid using the code:
datagrid1.item(rownumber,columnnumber)
using this write the query to fill the second grid at the form load event itself.
this is what i can think of. pls let me know if this works.
|
|
|
|
|
Your summary of what I was trying to do is correct.
This is what I found that works:
Dim button As Button = DataGrid1.SelectedItem.Cells(0).Controls(0)
varWhatever = button.Text
If I get the chance I will try your suggestion and get back to you

First count the no of row in dataset
dim rowno as integer = dataset.row.count
for rowno = 0 to rowno 'creating a loop
dim strval as string=datagrid.items(row#,coloum1).tostring
dim insert as string = "insert into table(field)values(strval)'write the insert command here
cmd1 = new oldbcommdbuilder(insert)
cmd1.nonexecutereader
next
hope it helps you
If you still have any questions let me know i will give you detailed explanation.
take care

hi ...
I'm familiar with vb6.0 but completely newbie in vb.net...
I'm interested in learning it, of course learning Object Oriented Programming methods by it not only vb.net syntaxes....
what is your opinion...? what is my first step? please help me
Thank you very much for any suggestion
Sonia

Sounds like you need to absorb as much material as possible.
Regarding object oriented programming, I suggest that you read books/articles on "design patterns". This is a very valuable skill to learn. In fact, you might want to take a class on this, because I think the best way to learn it is by practicing it. It's usually taught in C++ or Java, so watch out.
In regards to VB.NET, it's not enough to just learn the new syntax. You need to learn about the .NET framework as well. I highly recommend the following book (although it's for .NET 1.1):
"Programming Microsoft Visual Basic .NET, Version 2003"
http://www.amazon.com/gp/product/0735620598/qid=1133475906/sr=1-1/ref=sr_1_1/103-3239437-9033428?s=books&v=glance&n=283155[^]

Hello,
I made a simple Windows Form in VB.NET,
just a button, no code
because i'm new in VS2005 and was trying to see some features!
Now when trying to run this project, i get an error
"Error while trying to run project:unable to start debugging"
and now a translation of the explanation below
"the bindings entrance is invalid" ---- "de bindingsingang is ongeldig"
Don't know what to do know!
Thanks,
A.

just search Google for this: Error while trying to run project:unable to start debugging. There are many hits for that error most of which point to problems with the web server configuration. Maybe the type of project you are building is not a Windows application but a Web application? These are two different beasts.

Hi,
need help,
I created a vb6 program that utilized the ntservices component, so that it can run in windows services, i also include a timer control so that the program will run on a specified time, BUT i setup to run at 6am in the morning, PROBLEM my program does not activate on the specified time, is this anything got to do in Windows XP environment, but when i restarted the services, then my program will run. any recommendation on how to troubleshoot this problem, many thanks

I have tried to re schedule it at 8am, and it works, but when i schedule it about 6am, it does not work again. hmm any recommendation how to troubleshoot this problem, i was suspecting if its got to do with the power management?

How are you using the Timer? Are you checking the current time every minute with it or did you sent the Interval to the difference in time between when the service starts and the target time?

Yeah, i was actually checking the time every minute, program actually should run once everyday at 6.00am. if the program checks if 6:00am or greater, then it should run some procedure.
|
|
|
|
|
6 or GREATER??? It sounds like you either don't have a flag, or are not handling the flag properly that says you executed the procedure, so you don't execute it twice in the same day. Do you have conditions that reset that flag in your code?

I have checked the code, you kinda right its something to do with flag property, i think the culprit is the timer control, because once the program executed, i actually set the Timer1.Enabled = False, then forgot to turn it back on after the process has been completed.
thanks. hopefully this works.
