Hi,
I wanted to know if there is any way to call a method from just clicking a radio button without having to click on an apply button.
Thank you

The Click event may help you here. If you want something more efficient, which isn't called unless the checked value changes, use CheckedChanged or something like that

Hello,
I have developed one application, and added it to right click pop-up menu of the folder.
Whenever user right-clicks on folder and selects my application from pop-up menu, I want the path to that folder (on which user has done right click).
I am using Directory.GetCurrentDirectory(), but it gives me path to the parent directory of the user right clicked directory.
How can I get the path to the directory on which user has done right click?
Regards
Abhishek

Perhaps you could pass the folder name to the application. Presumably, you've added a registry entry in order to allow you to run something from Windows' context menu. Append %1 to the end of the program's registry entry and parse the folder name as a command argument

Make that "%1" (with the double quotes) so the path is allowed to contain spaces...

Horrible english, wrong forum, lack of information.
You get an F-, for doing nothing right at all.

To display PDF documents in my app I use the Adobe Active X component like this:
this.axAcroPDF1.LoadFile(@Filename);
this.axAcroPDF1.Show();
This works great for independent forms, but on a MDI form the component stays blank
After a lot of googling I found this in a VB forum:
================================================================
Your child form cannot directly refrence the Acro object like that.
instead of just using this.
AxAcroPDF1.LoadFile("C:\1.pdf")
you need to do it like this.
Form_ParentFormNameHere.AxAcroPDF1.LoadFile("C:\1.pdf")
=================================================================
I've tried to translate this to C# but have to confess I have no clue how to, and also one of the other messages said this solution doesn't work anyhow.
Anybody knows how to do this ?
Thanks in advance

Hi all,
I have encountered a rather nasty bug that I have no idea how to fix. I'm getting this exception when trying to create a foreach loop on a COM object. The type I am using for my variable is an interface.
For clarity, here is the basic structure of the code. I am using hte information stored in the individual messages to build a log of the operations performed by my program, which is a batch file verification tool.
foreach (KeyValuePair<fileinfo,> kvp in messages)<br />
{<br />
foreach (IMessage msg in kvp.Value)
{<br />
}<br />
}
The exception is thrown on the cast to IMessage in the second loop. I have tried casting to object as well but get the same error. I have also tried avoiding the foreach loop and working with GetEnumerator() directly (not generic), but the GetEnumerator method fails with the same exception.
Occasionaly, the loop will succeed in the cast, but I get even more obtuse exceptions thrown when I try to use the object. This happens seemingly at random. The exceptions are generally something to do with an unrecognised HRESULT or an unavailable RPC server connection, which makes no sense to me, as the application is stand-alone and does not require net access.
The strangest thing for me is that the code actually works in an older version of the program and there have been minimal changes to the class since then. If anything, it has become simpler to allow me to integrate it with other components and a log viewer.
I have found a proposed solutions on the Internet to import some keys to the registry, but I already have those keys in the correct location, so my problem appears to be different. I have never used InstallShield on this machine, so that can't have corrupted my settings as far as I can tell.
Also perplexing is how my primitive error handling code fails to work, where it once did. I get a null reference after the ErrorPage has been created when calling NavigationService.Navigate.
catch (Exception ex)<br />
{<br />
Debug.WriteLine("Fatal Error Encountered\n\n {0}", ex.Message);<br />
ErrorPage ep = new ErrorPage(ex);<br />
this.NavigationService.Navigate(ep);<br />
IsUIEnabled = true;<br />
}
I'm at a bit of a loss on this. Can anyone help?

Hi guys,
I m using a datagridview to show some data from sql server database.
I made the rows in designer and bounded the datagridview to my database.
It works great except one thing:
the datagridview gets new columns according the columns to datatable. It doesn't use the columns that i alread made.
I tried 'SELECT ColumnName as datagridViewColumnName' bud still not working.
Anyone a idea how to fix this?
Thanks a lot.

There is a setting to auto generate columns, turn that off. Then make sure each column is correctly bound.
Need custom software developed? I do C# development and consulting all over the United States.
If you don't ask questions the answers won't stand in your way.
Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.

Thanks for reply Ennis,
I set the autogenerate columns, bud now can't see the data in the datagridview. I have 3 records in my table. The grid shows 3 empty rows

Excellent. Now you just need to bind the rows correctly. Since you are using the designer there should be a property for DataItem with the column definitions. Set that to the column name you want to bind to. (I am guessing at the names because I haven't used Databinding in years but all of them work about the same)

I did this to look at the code, i exactlly copied and paste the names of the columns of the datagridview into the query. Still 3 empty rows:
SqlConnection mycon1 = new SqlConnection(connString);
SqlCommand mycom1 = new SqlCommand();
mycom1.CommandText = "SELECT CONTR_NR as contrId, " +
" CONTR_PROCOUNT as contrProCount, CONTR_TOTPRICE as contrTotPrice FROM Contracts WHERE CONTR_CU_ID='" + custNr + "' ";
myda1 = new SqlDataAdapter(mycom1.CommandText, mycon1);
mycb = new SqlCommandBuilder(myda1);
mydt1 = new DataTable();
myda1.Fill(mydt1);
mybs = new BindingSource();
mybs.DataSource = mydt1;
mf.dgvContr.DataSource = mybs;
And im sure that i have 3 records in my table

Yes but you have to bind the grid view columns using the data item property. Maybe you have them setup as unbound columns? The visual wizard lets you pick from a list of column names.
