Windows Forms

Did you follow the link Eddy supplied "Walkthrough: Hosting a Windows Presentation Foundation Control in Windows Forms" seems to cover it.

Why have you reposted this question with the same incorrect code? A number of people have explained what is wrong with this code and what needs to be changed. Please try what you have been advised to do rather than merely asking the original question in a different forum.

override the onpaint method of the picturebox and program the effect by your self check drawing images with GDI or GDI++

Thanks , I will check that ...

What is it that you do want? 2. Assuming you want 'b' to have some usable value, then you need to define b in the outer scope, and also break out of the loop when you hit the right value. Perhaps you could clarify your question?

Ya Thanks

if you want to force the user to correct any problem, then your validation code should: - tell your user what is wrong - tell your user he should fix it - disable everything that looks like it is accepting the data as is, including OK, Save and Close buttons - keep a Cancel button enabled, so the user can still abandon everything :) Luc Pattyn Local announcement (Antwerp region): Lange Wapper?

still could not figure it out is this impossible :((

then clearly the problem is that the column in the DataTable is readonly, so presumably it is in the underlying database. Trying to change the ReadOnly property in your DataGridView cannot possibly alter this. You have to investigate, and find out why the underlying data is readonly. DataColumn has a ReadOnly property and maybe this is being set to true somewhere else in your code. There are loads and loads of possible reasons, but from the error message, it clearly is not the DataGridView that is causing the problem. Henry Minute Do not read medical books!

because drawing in memory’s speed is much slower than showing to screen. lead to Delay. iam so glad to see you override the 'OnPaintBackgound ', 1) but i think you should can set 'form's double buffer property' to 'true', 2) or use a 'bitmap' to simulate 'double buffer'.
