update gdi before gui_show

greymouse · March 14, 2011

So i have a problem to load GDI graphic before the label has been shown.

How do i fix so it works?

Here is the code + extra files.

Try this:

Hmm, it doesn't do what i want.

When i click on the minimap it should open the minimap and close when i click the 2nd time. (Also hide/show the label)

But before the opening it should generate the GDI. So it's already done. Now it's just like before.

I got it to work if i use this method, ugly but works.

Edit: Now i can't have it smaller, ooh this is so bad.

I updated the code from post#2. Is this what you want to do?

Yes like that, but instead of the wolf been creating when you press minimap.

It should be created before. So it's already done. So you don't see when the pixels loads.

UEZ · March 14, 2011

Ok, another try then. Look again to post#2.

Works really nice. It's nice from you to give the whole code too.

And one more thing. The minimap is going to be updated when everyone click on the minimap.

People drawing and it saving the colors, and the minimap need to clear the recent picture.

And one more thing. How do i remove the rectangle when i close the minimap?

I only come to this stage, then didn't i understand how i should create it.

Well, as it is descriped it excludes GUI controls from GDI+ graphic screen. E.g. move the button over the picture and it will not be erased when the picture will be refreshed.

And one more thing. The minimap is going to be updated when everyone click on the minimap.
People drawing and it saving the colors, and the minimap need to clear the recent picture.

I don't understand you exactly what you want!

And one more thing. How do i remove the rectangle when i close the minimap?
I only come to this stage, then didn't i understand how i should create it.

Also here, I don't understand what you mean with "remove the rectangle when i close the minimap"!

I mean, it should close the minimap.

And then open it. Not be open forever.

^ And here is what i want it to be ^

With the pixels that "BitmapCreateFromScan0" saves.

Need to be cleared. Because if i load a new "text2.txt" it's will not be cleared.

^ Here is the example for that, test2.txt added as attachment. ^

Look to post#2 again. I hope this is what you want.

Now it is your turn to fine tune the code to fullfill your needs.
