Does anyone know how to create a tooltip popup when we point a mouse over a "text" for a period of time. This is normally seen in visual studio. When we point the mouse on a function name or so for a period of time, it will show its declaration in a small tooltip popup window. How can we customize this to show some tooltip information, upon pointing to some of the words for which we want some info. I want to create this as plugin/add-in in
Visual Studio .NET so that on pointing to certain words I can get some information about those words.Coding in either VC++/C#(preferrably VC++). I need some help for this urgently...can anyone help me out???

Why don't you try the same using the key strokes, like Ctrl+Shift+Space or something.
One thing i can you can try is, to load all the Words and corresponding toot tips,(when u load the file) and then over write MFC's tool tips. but Iam not exactly sure of wat function is to be over written. May be you can try on TVN_GETINFOTIP.. 
thnx,

I am using 2 images, one at a time. Is there a way to hide the other image while the other one is visible?
Thanks for all the help!

Are the images part of a static or picture control? If so, just use ShowWindow(SW_HIDE).

This does not work. I've already tried this one.

hi folks,
ok, i hope i can describe this in a way that will be understandable 
so here's what i plan to do: i want to display a splash screen with an alpha channel. neither the bitmaps rectangle nor the surrounding color of my graphic should visible. i.e. i need to set the surrounding color to be drawn 100% transparent. not difficult so far. but here's the tough part. namely, i want the splash screen to appear like it comes from nowhere. it should start with a opacity of 0% (i.e. 100% transparence) and within a few seconds it should become more and more visible until it has a final opacity of 100%. confused ? me too 
i'm only able to display the graphic without the surrounding stuff (alpha value) when the graphics opacity is set to 100%. but when it comes to the piont where i need to set the opacity to a lower value and still want to make the surrounding color of my graphic completely invisible i'm starting to freak out. i don't know how to achieve this.
i would be very glad about some hints ... any hints 
thanks in advance.

Some ideas:
1: Do a screen grab of the area your splash screen will cover. In memory use the grabbed bitmap as the background, draw your splash screen on it. Blit that bitmap to the screen. Not true transparency, but it will appear that way to the user.
2: Use a window region (HRGN) that corresponds to the opaque part of your splash screen.

nice idea, actually. and i've already tried it. there is just one problem. the graphic i want to show is not rectangular (neither elliptic) it's a custom hand drawn one. so if i draw my splash on the background image and make it slightly transparent the whole graphic (including the surrounding alpha color) will be visible on it. you understand ? but the alpha color should be complete invisible during the entire appearance procedure.

Use an intermediate step. Use two memory bitmaps containing the background image. On one draw your splash screen with TransparentBlt() (Image is 100% opaque, alpha colour 100% transparent), then draw that image at the transparency you want onto the second bitmap. Because the "transparent" parts are the same colour the alpha blending will appear transparent.
As for the window region idea, you should be able to adapt the code found at http://www.codeproject.com/buttonctrl/irregular_buttons.asp[^] to create the reguired window region for your splash screen.

yeah. i use it already.
AlphaBlend and SetLayeredWindowAttributes are the two main functions with those i'm trying to get this done. But they don't last out.

selecting rectangular bitmaps and AlphaBlending them is not my problem. i need to get it done with non-rectangular bitmaps.

I have a button in my dialog. When I disable it using m_button.EnableWindow(FALSE) while other control has the focus, other control loses the focus it seems the disabled button gets the focus because after pressing arrow key the control next to button gets focus.
Is this by desing or some bug ? How to avoid this ? SetFocus() to previous control does not work 
Thanks !

There's more to this than what you've provided. I was able to create a dialog-based project with three controls. The first control has the initial focus. When I disabled the second control, focus remained on the first control. Pressing the Tab key changed focus to the third control.

I have combo box control (1st control) . When you change current selection using arrow keys, OnSelectionChanged handler will recognize that certain item was selected and will call EnableWindow(FALSE) to some another button (2nd control). When you hit down arrow key again, instead of changing current combo box item, the 3rd control in the dialog is focused

Something else is still at play here. I duplicated your layout and it still worked fine. Your best bet is to create a temporary dialog-based project with just those three controls on the dialog template, and a ON_CBN_SELCHANGE() handler. What does that yield?

Thank you for your time ! Clean dialog works for me too, I'll find out what's going on in my project.
thank you !![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Hi guys,
I've been trying to load bitmaps into my dialog. I have one picture control and i have 2 bitmaps that i want to use.
this is part my code in general:
if (Firstsituation)
{
thisimage.SetBitmap(bmp1);
}
else
{
thisimage.SetBitmap(bmp2);
}
I'm wondering why it keeps on loading the image i have at default at my picture control properties. I just can't load them the way I want them to.
Even when I remove the code for LoadBitmap(CONTROL), it still executes the project, though a bit of code is missing. Anyone who can enlighten me? I'm kinda confused.
