You can use Refresh()
or use Event OnPaint()

Since when?
Every control has it's own Paint event.

Then use the PictureBox.Paint event - if you must use a picture box at all, rather than painting on the form directly. If you Google for "PictureBox.Paint" the first link is the MSDN example of how to paint on a picturebox[^]

C# repaint equivalent is Invalidate.

hi.i try delete all data in my database but database size not change.why?
please help me to resize my database.

Hi,
databases don't simply grow and shrink as you add or remove data; they will grow in rather large steps, and typically they only shrink when you give a command to compress the database; this reorganizes the entire data storage and may take a while.

Hi,
When I do request from web browser my cookies look like this:
Cookies/Login:
CLIENT_WIDTH_DIR=1276
CLIENT_WIDTH_DIR=250
CLIENT_WIDTH=250
MAIN_WIDTH_DIR=1066
MAIN_WIDTH_DIR=60
MAIN_WIDTH=60
PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173
But when I use the following code:
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH_DIR=1276");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH_DIR=250");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH=250");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH_DIR=1066");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH_DIR=60");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH=60");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173");
the cookies look like:
CLIENT_WIDTH_DIR
1276,CLIENT_WIDTH_DIR=250,CLIENT_WIDTH=250,MAIN_WIDTH_DIR=1066,MAIN_WIDTH_DIR=60,MAIN_WIDTH=60,PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173
2 lines, broken, instead of 7 and, of course, session id is wrong and nothing works.
How I can set the cookies right?
Thanks.

Is your c++ library COM or native library?
See the samples here for calling native libary from .NET and here using COM objects into managed code.

i don't know, that'as why i ask.
i simply added a basic (not ATL, MFC or whatever) c++ class library project to my c# project.

I suppose your library is native.Follow this link for quick and easy sample how to consume C/C++ code in C#.

Hello,
I've got a main form and a status form. The status form is displayed non-modally (Show method), and updated using Application.DoEvents() while working on a bigger job.
Now the problem is that the main form is not blocked while performing the job. Both the status form and the main form can be focused. What I'd like to have is that the main form is blocked and redirects the focus to the status form, just like it would be the case for modal dialogs. Is this possible?
I tried setting the Owner property of the status form to the main form, but it didn't have any effect. The ParentForm property is read only, and the Parent property only applies to standard controls, not forms...
Thanks and best regards
Dominik
PS: Moving the job to another thread isn't possible.

I've now implemented the following: when the main form runs into the Activated event, I'm calling the Activate method of the status form.
This way the main form is somewhat blocked, but there's still the disadvantage that visually the main form still draws the controls as if they could get the focus (for example the main menu items are highlighted when hovering over them). If you know a way how to disable/solve this, please let me know.
Thanks and best regards
Dominik

can't you try to add a this.Click event to the form and captures the user's click and bring the focus the other form?

See above
Thanks for the reply anyway, best regards

you can also use panels in the mainform, switch to a panel with the text 'please wait' and switch back after your other jobs finish.

Yes, this prevents visual effects on hovering, but also grays out all dialog elements (which is actually good I guess).
Thanks and best regards
