In addition to all the advice you've been given, please pick a relevant subject. This is the C# forum after all, can you imagine what it would look like if every thread were to have the subject "C#" ?
Cheers,
Vikram. (Proud to have finally cracked a CCC!)

Hi All,
I'm working on a project where on the left hand side of the form i have a treeview control and bottom to that i have some buttons. When user clicks on the node then i'm loading respective user control on to the right hand side of the form.
The issue here is i have two save buttons one on user control and other on the main form just below the treeview control. I have the code to capture the key press :
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == (Keys.Control | Keys.S))
{
MessageBox.Show("Do Something");
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
Here this code works only for the main form but not for the user control.
Please let me know how can i capture the key press event for usercontrol so that i can call save event of usercontrol.
Thanks in Advance
Regards,
Prakash N

Set the property KeyPreview in main form to true, then you can get always the event "KeyDown".

Use this
DropDownList2.Items.Add(New ListItem(dr[0].ToString(),dr[0].ToString());

Why you are writing code in SelectedIndexChanged event of the same control.
ankitjain1110 wrote: DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
Write this code on form's or another control's event.
Like on Form's Load event....

I've plenty of Rectangles in an image and I want to grab events on each MouseEnter and MouseLeave. I tried with a bool for each rectangle and set it true when Cursor gets in and set false when gets out but that things buggy when Rectangles are overlapping...thats why I'm looking for another way. Any idea ?

probably you must use event mouseMove and check if mouse pointer is inside rectangles. overlapping should be no problem anymore.
|
|
|
|

how can you say overlapping wont be problem ? BTW I'm using WndProc and WM_MOUSEMOVE

.NET has a method/event for it. Put your image in a pictureBox and use event Paint and MouseMove.
I would avoid WndProc and Windows Messaging if .NET provide some method for it.

You can use web services provided by sql server reporting services.

Ok,
Any tip on how. I've searched for articles with code samples but have not found any.

Hi everyone!
I have fixed sized form having ToolStripContainer that contains bottom and top ToolStripPanel.
I have 2 toolstrips and my contentpanel is designed when they were in single row. Now at runtime when I changed a toolstrip to another row of container my form contents get hidden behind the boundary of form.
This happens also when I change one of toolstrip to bottom ToolStripPanel as well. The bottom panel hides few buttons in ContentPanel.
How I can keep the visibility of my ContentPanel in these scenarios.
Thanks.
Good Day.

System.Data.OleDb.OleDbException: Data type mismatch in criteria expression.
Source Error:
Line 84: string cmd2 = "select Description from description_details where Group_id="+str_group +"";
Line 85: da1.SelectCommand = new OleDbCommand(cmd2, con1);
Line 86: da1.Fill(ds1,"group");
Line 87: DataTable dt1 = ds1.Tables["group"];
Line 88: descrptndpdnlt.DataSource = dt1;
Why is it showing error in line 86???

Actually your prob is here
myinstincts wrote: Line 84: string cmd2 = "select Description from description_details where Group_id="+str_group +"";
Single Quote is missing...
Replace this with following...
string cmd2 = "select Description from description_details where Group_id='"+str_group +"'";

If Group_ID data type is numeric then build your sql query as:
Line 84: string cmd2 = "select Description from description_details where Group_id="+str_group;
If Group_ID data type is char (text type) then build your sql query(variable should be in single quotation) as:
Line 84: string cmd2 = "select Description from description_details where Group_id='"+str_group + "'";
Hope this will fix your problem.
