Error C1900 with static library

I am trying to use a static library that, although it is meant to be for VC8 produces the following error when build the suppliers sample application:

Linking...<br />
fatal error C1900: Il mismatch between 'P1' version '20060201' and 'P2' version '20050411'<br />
LINK : fatal error LNK1257: code generation failed

I don't have the source for this library, any suggestions?

Looks like it can be related to Service Packs or even Visual Studio Installation problem that might require a re-installation.

The dates are one day apart and the package versions are the same, good idea though.
Thanks.

This[^] gives a possible cause, the static library is built with the /GL switch so no linking is done when the librry itself is built, only when the library is linked into the project. Dead | X|

All I have to do is get the library rebuilt without '/GL' and see if it works.

GDI+ equivalent of SetROP2 (R2_NOT)

I'm hoping I'm just being dumb, and someone will point out the command I've missed...

I'm trying to draw a shape onto a DC using GDI+. I can change alphablends, colours, line thicknesses, etc, (see my http://www.codeproject.com/KB/miscctrl/generic_picker.aspx[^] article for drawing examples).

But what I can't work out how to do is to make an "invert" brush / pen.

Ideally, I'd like to blend a colour with an inverse of the below colour, but just plain inverting the original colour is good enough for me.

Thanks,

Iain.

It does enforce what I've learnt from further digging...

Basically, the ROP modes do not exist. There articles here on CP, but you have to get a fresh DC from the graphics object, and use classic GDI code on them...

Ah well, roll on Direct2d! (Not really, unless it can be run on XP, which the VAST majority of my customers have).

I don't understand anything from your question.
If you want to get the selected item, you can use CListCtrl::GetSelectionMark().

Does that work on a single-select list control?

Sure it does. I do it all the time. Smile | :)

But I realized that it does only recently.
Until then I used to do CListCtrl::GetFirstSelectedItemPosition and CListCtrl::GetNextSelectedItem

Hi,
I have created Dialog box in my application.I have added Scroll bar to that dialog.I am displaying images on that dialog( 8 Images for one scroll).If I Scrolling down I am seeing flickers on dialog box images.
Can any one help me.

How are you scrolling the images?

I assume you're first clearing all images and then redrawing them.
Try not to erase the diagrams first. Just draw over the diagrams.

First I am creating static control.I am taking this code in for loop

myStatic[i] = new CStatic
myStatic[i]->Create(_T(""),WS_CHILD|WS_VISIBLE|SS_BITMAP,
			          CRect(x1,y1,x2,y2),this);

After that I am using that static control for displaying Image.

myStatic[i]->SetBitmap(hbmp);

I am placing this code in one function called "DisplayImages".
I am calling this function for every Scroll.For every scroll I am displaying 8 Images as I told before.

I am not clearing all Images.I am creating new 8 Static controls at same
place on Dialog and I am using satic controls for Displaying new images.

One solution is double buffering. In your OnPaint () handler make a bitmap as big as your dialog and draw the images on that bitmap. Then draw that bitmap in one operation on the dialog using the CDC member.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
