You can set the text like this:
dataGridView.Rows[rowIndex].HeaderCell.Value = "Some value";
|
|
|
|
|
i want to add a control programatically to topleftheadercell but i m unable to do so.any idea?
|
|
|
|
|
AFAIK, there is no direct way of adding controls to that cell. You will have to Paint a control yourself within the region of that cell.

does object class implements IDisposable interface.
|
|
|
|
|
|
An easy way to find out. Create an instance of the object class and then see if it has a Dispose() method.
IDisposable will always force the implementer to provide the Dispose() method.
Object obj = new Object();
obj.Dispose();
|
|
|
|
|
There are plenty of ways to find these kinds of things. Simplest one being - pressing F12 while cursor blinks on the class name (or any word for that matter). It navigates to the definition.

It's kind of unlikely now, isn't it. All classes derive from object, so this would mean that all classes were (by default) disposable.

I have a main project which is in vc++
on click of menu i m displaying my c# form
if i use Form1.show my the form will allow me to access the main form also. but if i click the menu again form1 will duplicate
for correcting this i used form1.showDialog() . now it is showing only one form at a time. but i m not able to acess my main form as this form1 is shown as modal form.
is there any way to restrict the duplication

In your main form, keep a reference to the instance of Form1. The first time you display Form1, save the reference. When you dismiss Form1, clear the reference.
In the main form's menu handler, check if the reference is null, and create a new instance of Form1 only if it is in fact null.

i didnt understand sorry
what u mean by a reference
|
|
|
|
|
Use the Show method instead of ShowDialog. In the method from where you are showing the form, check if Form1 is already open. If yes, just bring it to front.

Thanks danish
Now i am using a loop like this
foreach (Form chkForm in Application.OpenForms)
{
if (chkForm.Name == "XXXXXXXX")
{
blnFormExists = true;
chkForm.BringToFront();
break;
}
}
is there any direct method to find the form is opend
instead of running a loop
|
|
|
|
|
Have a class level object for the Form1 and check if it is null in the method where you show it. Something like this:
public class SomeClass{
Form1 frm;
public void SomeMethod(){
if(frm == null){
frm = new Form1();
frm.Show();
}
else{
frm.BringToFront();
}
}
}

use the FileInfo in conjuction with DirectoryInfo:
DirectoryInfo di = new DirectoryInfo("your directory here");
var files = from fi in di.GetFiles("*", SearchOption.AllDirectories)
orderby fi.CreationTime.TimeOfDay
orderby fi.CreationTime.Date
orderby fi.Extension
select fi;

Hello Everybody.
I've created a control (MultiColumnToolbar) which contains 3 columns(ToolbarColumn | Left,Center,Right). Those columns contain my buttons and render a background. I've created 3 designers (MultiColumnToolbar, ToolbarColumnDesigner, ToolbarItemDesigner) which provide some DesignerVerbs for adjusting properties and creating elements.
My problem is that ToolbarColumns are set into designmode. Only if I open the MultiColumnToolbar.cs in designmode (control) and place a ToolBarColumn on the surface the ToolbarColumnDesigneris activated. It seems it's because the columns are created in the Toolbar and are not part of the target form.
The ControlDesigner provides a method EnableDesignMode to solve the described problem for sub-controls. Is there a way to enable the DesignMode for those sub-components?

Hi,
I am having problems with the background of the image after it has been rotated and then saved.
It saves the rotated image fine but it has a black background but i would like it to be transparent, similar to what occurs under Windows Operating System.
I tried using MakeTransparent method before but doesnt seem to work.
Here is the code:
Bitmap temp = (Bitmap)ActualImage;
Color c = temp.GetPixel(1,1);
temp.MakeTransparent(c);
.......
sfdlg.SaveImage(sfdlg.FileName,temp,80);
Could anybody assist me with this please?
Thanks

I don't know what method you use there to save your file, but my guess is you save it as a bitmap (bmp).
If so, then I must inform you that bitmaps (bmp files) do not support transparency... the gif and png file format on the other hand supports transparency.
I have no smart signature yet...
