Sounds like you're building an OO nightmare. Why would you need all these controllers ?
The way I'd do it is to add delegates that hook the controller to the UI, so the controller can call methods which change the state of the app, the presentation layer ( the form ) should be responsible for how that data is displayed, for example, in a tree view.
Actually, I was assuming you're using MVC, but you can't be, the controller is all about accepting input, which has nothing to do with how the view is rendered at all. What do you mean by controller ?

Well im using delegates to hook up the controller to the UI, this all works fine for me in a simple scenario (one view, one controller). But now im trying to do a more realistic scenario with a couple of forms (mdiparent/childs). As I understand it you typically have one controller for each set of related functionality. Then one controller should be able to handle user input and call methods on different forms?

I wana add Picture to datagrid with respect of every category..
etc is the category is Mobile i want mobile picture to be displayed in datagrid..
Does any have the code

Your question (despite being asked twice) is incomplete. You can show any picture you want, the question is, how are you determining the category ? Is this a windows application, or a web app ?

OK, then you should be asking in the ASP.NET forum, or you should at least make that clear. Otherwise, the answers you get will be no good.
You need to put an img tag in the template for a column of your grid, and set the URL to the image based on the data member that tells you the category. So you'd have a method that's passed the data and returns the URL of the image.

I'm not sure of the question. You can put any path you want in to Process.Start.

Why do you need an array ? A web page has a controls array already, although it's nested.
To put a page in an exact position on a web form, you need to use CSS to position it. Otherwise, it will use a standard HTML 'flow' layout.

Hi
I have created an application with transparent main window that displays some text. To initially display and change the text, I use the following code:
if (behavior.IsVisible)
{
Show();
mImage = new Bitmap(Width, Height);
Graphics dc = Graphics.FromHwnd(Handle);
dc.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixelGridFit;
SizeF size = dc.MeasureString(behavior.DisplayText, behavior.Font);
dc.Dispose();
Height = (int)size.Height + 1;
Width = (int)size.Width + 1;
mImage = new Bitmap(Width, Height);
dc = Graphics.FromImage(mImage);
dc.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixelGridFit;
Color background = (behavior.Color.ToArgb() == Color.White.ToArgb()) ? Color.Black : Color.White;
dc.Clear(background);
dc.DrawString(behavior.DisplayText, behavior.Font, new SolidBrush(behavior.Color), 0, 0);
mTextColor = behavior.Color.ToArgb();
dc.Dispose();
BackgroundImage = mImage;
TransparencyKey = background;
}
else
{
Hide();
BackgroundImage = null;
}
For some reason the window shows transparent on my PC and at least one other, while on most I still get a white background (i.e. no transparency). The only difference I can think of is that on the PCs where the transparency displays correctly, VS2005 is installed, while it's VS2003 or none on the others (I'm using latest video drivers etc).
Does anyone know of this issue and how to fix it?
Thanks,
Dmitry

I'm not 100% sure, but I think that transparent windows can only be rendered in Windows XP.
|
|

|

You are correct, but I am talking all XP SP2 PCs here, its 2007 
I think it is probably different DLL versions, like different common controls DLL, but I don't know where to start and what to look for.

Hello,
Had the same problem and if you search in google or msdn you will find a lot of other people sharing it.
What I found out is, that it has something todo with the graphic card and the Color quality (16bit or 32 bit).
I use the MakeTransparent method of the Bitmap class instead.
This works fine for me!
Color transparentcolor = bkgrnd.GetPixel(0,0);
BackgroundImage.MakeTransparent(transparentcolor);
Hope it helps!
All the best,
Martin

I have seen the postings of other people, however those that do have a solution are for C or Java. One of them talks about disabling DirectDraw acceleration for the application. It would be fine with me, but I could not find a way to do it in C# (no search results whatsoever).
I have tried MakeTransparent, but it doesn't work at all - now I see a background painted grey ("transparent" color) on all computers.  Can you explain more how you are using it so it works?
Thanks,
Dmitry

Hello,
I'm using it for Forms with a BackgroundImage.
This Image has rounded edges with a special color, which is not used in other regions of the Image.
I don't use the TransparencyKey property at all!
Bitmap bkgrnd = new Bitmap(myimagepath);
Color transparentcolor = bkgrnd.GetPixel(0,0);
bkgrnd.MakeTransparent(transparentcolor );
this.BackgroundImage = bkgrnd;
Hope it helps!
All the best,
Martin

I don't know why, it just doesn't work. Myabe I'm doing something wrong...
Resources.StartUpPicture.MakeTransparent(Color.FromArgb(80, 80, 80));
//or
//Color transparentColor = Resources.StartUpPicture.GetPixel(0, 0);
//Resources.StartUpPicture.MakeTransparent(transparentColor);
//doesn't matter, I know the color values
this.BackgroundImage = Resources.StartUpPicture;
this.BackgroundImageLayout = ImageLayout.Stretch;

Sorry, I meant what's the effect you see right now?
I don't know if working with the Resources is ok.

Allright, it works this way
Bitmap bmp = (Bitmap)Resources.StartUpPicture.Clone();
bmp.MakeTransparent(Color.FromArgb(80,80,80));
this.BackgroundImage = bmp;// Resources.StartUpPicture;
this.BackgroundImageLayout = ImageLayout.Stretch;
But behind the transparent image, there is still gray form background... And I need to make it transparent too, thats why I used the TransparencyKey.
Anyway thanx for help

I have the same thing at my form!
Don't use the TransparencyKey!

I don't know what this does, maybe just for test reason, leave it out.
All the best,

That's for stretching the image to form's size. I can't leave it out (tried and didn't help)
Anyway, why do you think Bitmap.MakeTransparent() will changed form's background to transparent? Imagine that you have black image with red triangle within, and you want to use it as triangle startup Form(with no borders, buttons etc..) . Just setting the black color on image as transparent will cause to display square Form with default background and red triangle within (instead black form with red triangle). In my point of view you have two options. You can changed the Form.Region value to display only triangle (which is not so difficult in this case), or use TransparencyKey. Image I use is almost impossible to describe in Region (many diffrent shapes) , so I have only one option left -> TransparencyKey.
Or do you know any other ways to do that?

What I'm having is a image which fills completely the Form.
The Form also has a gray Bockground.
Then I "MakeTransparent" with a special color, and at the reagon (at the rounded edge) on the bitmap, where the special color was, my Form also shows the things which are under the Form (not my gray Background).
Maybe there is a propblem because you are doing the stretching after the MakeTransparent.
Try the stretching before.
All the best,
Martin

I tried to put it before or remove it. No change. I'll probobly stick with TransparencyKey, which by the way I use on one more place-> Trasparent Flash player. So I need to make it work
