Hi,
Can anyone help me in parsing a value from a datgagrid into a textbox?
Let's say a datagrid with colums (lastname, firstname, id)
i want to take lastname from the grid and put it in textbox.
for ex. textbox.text=datagrid.currentrow.selected.equals(lastname)
when i do this, it return a boolean expression..
Please me on this.
thanks in advance..

Did you try: textbox.Text = DataGridView1.Item("LastName", 1).Value

Hi,
Yes I tried it but I got an exception( Index was out of range.Must be non-negative and less than the size of the collection. Parameter: Index)
thanks again
|
|
|
|
|
OK, well, how are you choosing the index? You must be passing one that's out of range.

Hi,
I have a datagridview with the following columns( ID,Title,Las_name, First_Name, Middle_name)
Lastnamelabel.text=datagridview.item("Last_name",2)
I did it this way I got the exception..
Thanks

Well, assuming that you actually spelled Las_name correctly in the column definition, are you sure you have at least 3 rows (0, 1 and 2) in your grid?

Hi,
Thanks a lot..
It works if one row. what if you have more than one row and want to list all the last_name into a listBox..
OR you want to select a particular row and parse its value.
Thanks

To get a different row, just put the row index in the Item method. To get all the rows, loop through them all in a For loop or a For Each loop and add them wherever you want.
You know, this stuff is covered in beginning books and tutorials.

Nah. Those tend to be boring and cause head aches. Anyway it's way easier to get a personal coach who reads aloud the relevant sentences, and types in useful hyperlinks ...

Unfortunately, I never found a personal coach like that. 
I'll bet you didn't, either?

Hi,
you have been very helpfull and kind.
Thanks for letting me lit my candle in your knowledge..

the Equals method checks for equality, so it answers a yes/no question and returns a boolean. That is not the way to copy some data. You need to access the right cell of the grid, take its value, and fit that into the textbox; if the value isn't a string, apply ToString().

Hi,
Thanks..but can you guide me a bit?

you should learn to collect information from the official sources first; those would include:
- your course book on VB.NET and Windows programming;
- MSDN;
- Google;
- CodeProject articles.
If you studied those, and still have a problem, feel free to ask a good question here, and lots of people will help out.

Thanks for your advice..I will do that and continue to do that. One can never stop learning.
Best regard..
PS. will you guide me?

i have a vc++ code which are a drawing program.
how can i make it into an ocx so i can use it in vb.net??

You're in the wrong forum.
But, the control has to be written to support being compiled into an ActiveX control. If it's not, you'll have to rewrite it to support such. Ask further questions about this in the Visual C++ forum. It has nothing to do with VB.NET.

I need to successfully load and unload assemblies from my vb.net project in real time. Can anyone recommend a tutorial on this process?
Thanks!
|

I suggest you google around; look for "AppDomain", as you can't unload assemblies, all you can unload is an AppDomain, so you will have to load assemblies in a new AppDomain, then later unload that AppDomain.

Oh,sorry, yes I understand that this occurs through appdomains. And I've googled and binged my head off on this, but I have yet to find a good solid tutorial on the mechanisms of the process. I was hoping someone here might have a good book or link that would help me.
Thanks

I don't have any around here, however I would suggest you look at some of these[^].
That may be a little hard though with your head off.

Hello, (know this isn't directly related to vb but didn't know which forum to ask so any help would be appreciated)
I am getting an error from IIS AppPool when attempting to call a WCF service which accesses a table in sqlexpress that's local to my PC. Using server explorer, I can access the table just fine and took the connection string right from server explorer and plugged it into the connection string area of the web.config. What do I need to do with IIS to allow it?
ConnString-> Data Source=xxxxxxxx\SQLEXPRESS;Initial Catalog=GBUtilities;Integrated Security=True"
The Error is (also used default app pool - doesn't matter):
System.Data.SqlClient.SqlException was unhandled by user code<br />

In the connection string, try replacing Integrated Security=True with Uid=[user];Pwd=[password]
My advice is free, and you may get what you paid for.
