Do you want a control to have its focus set when the mouse moves over it? If so, any control should have an Enter and a Leave event for this exact purpose. Just register the event handler to set focus on enter.
thanks for your answers. I need just what a click do with focus. When you click the focus goes to this clicked place. the click event not work with this. I have not the name of the control to set the focus.
Im working with private web pages and i need to check them on screen just as user do. This web is encrypted, and i have not access to the html source. (that is almost empty).
I hope i explained this.
Here is what I want to do. I've got a combo box, which has lots of items, so selecting specific item takes some time. I'd like to use an intelliscence, bc that would make the input process faster: once the user starts typing the first letters, he is shown the items, which have the same starting letters. I've seen this done on many websites, but I haven't found any info for it.
Thanks for time and effort, I really appreciate your help.
Done that, thank you! I still can't seem to figure out couple of things, could yo help?
1. When I'm switching between mdi child forms it looks like the next one is maximizing - there's that blue windows title bar animating inside parent form briefly. How do I turn one child form off and activate new child form without visual artifacts, i.e. fast and smoothly?
2. I can't get rid of the (main?) menu strip at the top of the parent form, no matter how I try when I got mdi child forms. How do I remove that menu, which is not needed and makes the view look bad?

ok friends, i have drawn a rectangle on the display dc as specified in the first post, assume drawn over the system tray area. so now i use the below code to erase it. the code is perfect. but winodws does not react to it
My question is quite simple and i'm not sure there is a solution. But if you have any suggestions to go round, it would be great as i'm not really content of what i'm doing so far.
Here is the problem :
Let say you have a base form named FORM and 3 derived forms (FORM1...).
On the base form you have several controls (buttons, textbox, labels, more than 10) taking all space of the form.
On the derived forms you can see them all (design- and run-time)
Very easy so far.
Let say now that i wan't to replace a textbox by a combobox ONLY on FORM1.
I add my combobox at the right place, i make my textbox non-visible by setting the property and all is ok at run-time... but not in the designer ! where i don't have the place to put my inherited textbox cause it's still visible at design-time and my form is full of controls.
To make even more simple, i would like to prevent the designer from showing, in a particular derived form, a control inherited from a base form.
My "solution" for the moment is to set the location property of my textbox at "1000;1000" so it is not visible in the designer.
I suspect you must have some reasons for not doing this, but wouldn't this be more straightforward if you just stripped the controls from the base form that don't actually appear on all the derived forms, and just leave a hole where these replaceable controls go?
Actually I have 8 derived forms which use 15+ identical controls. But for 1 of these derived forms, 4 controls have to be replaced.
What you suggest, tell me if i'm wrong, is to remove these 4 controls from the base form and add them in each derived forms (7 here). But if i do that i'll loose the factorisation benefit for these controls.
That's a clean and acceptable solution since you don't have to deal with many controls on many derived forms. I simplified the example to make it clear but if i do that in my real case, i will multiply the depth of inheritance and the forms without a functional purpose.
I've seen this question in various forms in several places, but I have yet to see a satisfactory solution.
Using .Net Framework 2, I've got a DataSet with elements bound to several TextBoxes which are scattered on several tab pages on a form. I can then change any of the TextBox texts, and the corresponding changes do appear in the DataSet.
I want to enable an Apply button when any of these elements have changed. I tried to use the DataSet's HasChanges, but it will not return a 'true'. I also tried a RowChanged event on one of the DataTables in the DataSet, but it never triggered. I tried to resort to using the TextChanged event from all the TextBoxes. That almost works, but the event is raised when the binding initially sets the TextBox contents. I can tolerate that on the first tab page of my form, but the TextBoxes on the other tab pages don't get set until you initially select those tabs, and it is difficult to distinguish between a user-initiated change and the original setting.
Thanks for your suggestions.
