Hi
I think you can learn more about new features of the dataset in VS 2005.

Hi,
I am developing certain controls in C#. One of it is the datagrid control. I have used the horizontal and vertical scrollbars on the datagrid. Now I need to customize the scrollbar properties and change the color of both the scrollbars.
Have seen through several sites, however no solution is available. People have developed independent scrollbars, however I need something that can be integrated with the datagrid. Any help on the topic is very much appreciated.
Also any ideas on integration of existing custom scrollbar are apprciated.
Thanks and Regards,
Sanjay

There is no way of changing the color of the standard scrollbars, as threir apperance is decided by the color scheme that the users selects. If you want it do look different, you have to use a custom scrollbar control.

b { font-weight: normal; }

As Guffa pointed out, you can't really change the color of the Windows scrollbars. However, HTML gives you the option to customize the colors. So what you can do is display IE control on your Windows form!

Thanks Guffa, Malhar for your reply..
The application is a desktop application so cant use HTMl, CSS.
Also do anyone of u have any ideas , how to integrate a custom scrollbar (with the event etc). I have consructed a scrollbar, but I'm having difficuties integrating it..
Thanks and Regards,

Who says you can't use HTML/CSS in your desktop app? Desktop app means that your program is provided as an EXE file + some DLLs on client machines. Majority of the desktop apps I've worked display HTML/CSS. This hybrid format allow the user-interactivity of the win-app and run-time customization of data presentation (through XSLT/CSS). You can display browser control on your desktop app--you just have to add it from the Toolbox.

You can put a webbrowser control in a desktop app and feed it custom HTML to display. I know it's a kluge but if there isn't a way to override the grids scrollbars behavior it'd probably be less unpleasant than writing a custom control.
My thought would be, is it possible to do a custom paint of the scrollbars by overriding the OnPaint method?

The only way you can do this is by launching a new IE window, and selecting the toolbars you want to show.

Hi all,
on my form is a tabcontrol where the count of tabs depends on the access level of the users. So I have to add or remove tabs and must rebuild the whole tabcontrol. It results in a crazy visible rebuild flickering.
I there a method to avoid these visible rebuild activities on forms
somthing like
form.BeginRebuild()
...
form.EndRebuild()
Between these commands the should be quiet.
What can be done ?
Thank's in advance
Regards
Frank

Thank you for your quick answer,
I tried your suggestion, but the code doesn't changes anything on the reaction.
You can see the clearing and rebuilding of every tab of the tabcontrol.
Try this:
this.SuspendLayout();
this.TabControl.SuspendLayout();
TabControl.TabPages.Remove(Tab0);
TabControl.TabPages.Remove(Tab1);
TabControl.TabPages.Add(Tab0);
TabControl.TabPages.Add(Tab1);
this.TabControl.ResumeLayout();
this.ResumeLayout();
It doesn't suppresses the visible rebuild process.
Some ideas
Thanks

I have a button and the forms transparecy key is set to gray so any instances of the color gray and the form will set that so its transparant. BUT I have a button on top of a picture box and want the button to be transparent so you can see the picture box but not whats behind the form?
The button has an image and I want the grays areas to not be showen. How would you do this?
In the end we're all just the same

I have made a program to play video file in directx (directx.AudioVideoplayback)! It worked well ! But I couldn't find the way to handle the video.owner !
when I did set the video.Owner = (name of my panel); I wanted to set video to full screen mode by double click on the video (in bool property video.FullScreen).
I tried to add Double Click EventHandler to my panel or video.Owner but It didn't work !
How can I do this ? Any ideas ... ?

My understanding is that when you run an EXE, it gets compiled by NET in chunks as you use various parts of the application. This method of execution has advantages for some types of computing. But i have the NEED for SPEEED! This app needs to respond quickly to user interaction at all times as if it was already compiled. My app runs great once it is fully compiled, but is unacceptably slow until it gets to this fully compiled state.
Is there a way to instruct NET to precompile your EXE so that it runs at 100% speed from the start? If this causes the application loading to take longer, i accept this tradeoff as the app will start when the computer starts and i do not anticipate the user interacting with the app during this time.

try ngen.exe (native image generator)...it precompiles an assembly...
call it like this: ngen - install NameOfAssembly

There are various stages you are not considering, beside JIT compilation.
- initialization of static data
- initialaztion of instances
- CPU cache
To get everything precompiled (JIT'ed), use ngen on your assembly. I doubt that that will make as much difference as you hope for.
Static data is by far the biggest bottleneck.

leppie, thanks for your advice.
I precompiled my exe using Ngen.exe and no performance gain was observed. It makes sense since most of the assemblies used by my app are already precompiled NET assemblies. So i add Ngen.exe to my long book of Microsoft urban legends (myths).
I then tried a hack. I attempted to force precaching of forms by automating user interaction off-screen. I click buttons and cause forms to appear so they get cached. After this is done, the precached forms are presented to the user. Requires some dancing in the WndProc with custom messages. You need to wait until after the paint event to get the cached form. This works as long as the form is mostly visible on screen. When form is mostly offscreen, it does not work. This was a hopeful hack, but it came to a dead end.
So after a long trip i have concluded that C# and all the NET languages, is not significantly different than VB6 in GUI performance. This is a disappointment. Luckily i used mostly Win32 calls in my app and not NET equivalents and so porting to C++ will not be to much of a problem.

This not true.

If you really need perfomance, VC++ should be your choice, not .NET.
