Hi
I need report by crystalreport that the details of this report is:
This report is the result of a meeting that this report must show the subject of the meeting and members of the meeting and explanation of the meeting .I get this information from a dataset and this dataset has two datatableadapter.
One of this two datatableadapter is give me members of the meeting and another one has subject and explanation of meeting.
Maybe this report show several meeting and each meeting has one subject and one explanation but has several members and it must show each of the meeting separately.
What type of crystalreport should i choose during of the process of making a crystalreport?
Please somebody help me.

I think it is best if you create in design then the templates provide

What choice? Design view is where you drag and drop fields into report

How can I loop through every single toolstripmenuitem in a toolstrip, including the subitems of each item, and each of the subitems of that item, and each of the subitems of that item (with no set limit to how deep it can go)?

Make a function to call itself, but beware you can easly get infinitive loop if you are not careful.

Flood counting pixels (Counting pixels instead of filling with a color)

Thanks, wasn't think of it that way.

Hello.
Does someone have a simple sample for flood filling for a picture, or even better a sample of how to count the pixels instead.
What I want is to count the pixels with the same color that touch eachother. I saw some flood filling you could rewrite, but those are very complicated so a simple sample for that would also be great.

Hope you can help.

It's not complicated at all, just change the "colourPixel" or whatever they call it to "counter++" or something like that

Glass bordered Nonresizable window without title bar?

Re: Glass bordered Nonresizable window without title bar? [modified]

19-Dec-09 7:19

I'm trying to create a window with a border like the Intelli-sense one has under Vista/7
Example image

It has a glass border, no title bar and it IS NOT re-sizable
I've been trying all day to emulate this border style, even by copying the style Spy++ says it uses to no avail. (I even tried modifying CreateParams to use the parameters the window does- no luck)

How can I implement this kind of Window?

This kind of window is custom painted. Even the borders

Hi,

CodeProject hosts a lot of articles on progress bars, some or good, some not.

Progress can only be reported to the user if the operation consists of multiple steps and you know (or can somehow estimate) the relative duration of each step.

If OTOH your backup basically consists of a single SQL (or other) statement, then it is impossible to report progress as there are only two states: nothing done (before the statement) and all done (after the statement).

GDI Get Painted Points

I draw line on windows form, using following function.

private void DrawLine(Point pPoint, Point pFisrtPoint)
{
Graphics graph = this.CreateGraphics();
Pen pen = new Pen(Color.Red);
graph.DrawLine(pen, pPoint, pFisrtPoint);
}

How can I get painted points coordinates?

Luc Pattyn19-Dec-09 5:51

hi,

that is bad code for several reasons:
- when no longer needing objects that you created and have a Dispose() method should be disposed, especially the expensive ones such as a Graphics;
- Pens.Red is for free;
- within a Paint handler, the Graphics is for free, see PaintEventArgs.
- you should not use CreateGraphics except as a last resort.

I suggest you read this[^].

BTW: the pixels modified by a DrawLine are on or near the line you paint, which exactly depends on some parameters, such as SmoothingMode I guess.

What do you mean? you want to get coordinates of already pained point? (All points on screen are painted)

Or are you refering to?

pPoint.X
pPoint.Y

also Graph.TranslateTransform can affect your coordinate system

For example I write following code;

Point p1 = new Point(0, 0);
Point p2 = new Point(3, 0);

DrawLine(p1, p2);

I want to get painted Point;

"0,0", "0,1", "0,2", "0,3",

You'll need to implement you're own line drawing algorithm to return those points. There is nothing in the .NET Framework that will do it for you.

That's not strictly true - he could paint it onto a bitmap of the same size and examine the pixels.
