I'm guessing your InvalidateRect() call is causing a repaint that ends up covering up what you just drawed to the screen.
What is happening with your current code??

InvalidateRect doesn't work, the screen is still dirty.

Yes, you'd have to set the erase background flag to true in the call and call UpdateWindow() to force an immediate paint. That worked on older OSs but on Windows 7 the updates don't happen while you have the mouse button pressed it seems. It does work on the LBUTTONUP message (just tested it).
You may have to double buffer - grab the image for the rect from the screen, draw your rectangle, draw the captured image back to the screen to erase, etc.

Deja Voodoo. It almost feels like I posted an answer[^] to this problem some days back?
Use SetROP2 to rubberband it.
Yes, you can mix GDI and GDI+ together in the same application. You just need to understand how each works to make them complement each other.

Google for : Html encryption.
You will find product such as:
http://www.allynova.com/encrypt-web-pro-order.html
I guess that if you want to encrypt HTML page sent over the web, it would be the way to go...
Or also, you could check:
http://www.iwebtool.com/html_encrypter
This is not very secure but since your page as to be displayed anyhow, what is the purpose to encrypt it.
If the reason is for transport, then probably it should be sent over a securized connection.

What is the purpose to encrypt a HTML file ? And why HTML ?
If the purpose is to protect something on the web, then client side protection is very weak.

I have written an application in c# that has a reference to a dll written in c++. I can run the application in debug mode and it works great, but after I build the application, it will not start and gives me the following error, any thoughts on how to resolve this?

You need to at least narrow down whether it is the C# application or the C++ DLL.

Hi, thanks for the response. The event log indicates it is the c++ dll that is causing the error. What else would you like to know?
|
|
|
|

I have seen that error when you mix 64 and 32 bit platforms. The application and the dll need to agree on their "bitness". Check your build parameters for C# to see the platform selected. If it says "Any", that means that, at runtime, it will pick the architecture best for the machine you are running on. If the dll doesn't match that, you will get this error.

Thank you, I will try that on Monday when I get back to work and reply back with the results.

Sorry, I don't use Visual Studio Express. In Visual Studio 1008 Enterprise it's in the Project Properties, Build tab, Platform Target field. There's a setting for both Debug and for Release. Sorry I can't post a screenshot of the relevant screen.

After trying many different settings in VS 2008, I downloaded a different version of the helper dll that I was using and this seems to have fixed the issue. Thank you to the two people that replied.

I'm experimenting with D and I'm trying to make a resource manager much like the C# one.
Now I'm hitting a problem...
How do I know the current user locale? i.e. "en-Au" / "en" ?
I found this function: GetUserDefaultLocaleName
but apparently it's only post vista... what if my program run on XP? what should I do? (I'm trying to write an installer, so I'd like to cater, at least from XP tp 7!)
I found this one too: GetUserDefaultLCID() but what am I to do with a LCID?
Is there a referenc etable I can use?
[EDIT]I just found a big table with the exhaustive list of locale...
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

Have you tried GetLocaleInfo()?

I haven't. The fact it doesn't seems to work on vista and later where I should use GetLocalInfoEx() is a problem.
But I have an exhaustive dictionary of all LCID and and their code name, much better for me!

I'm not sure what you mean by this, but GetLocaleInfo() dates all the way back to Windows 2000, whereas GetLocaleInfoEx() works on Vista and newer.

#define MyTemplate( filename ) "D:/Template/MyApp/" # filename
#include MyTemplate( stdafx.h ) // failed to compile
int main()
{
cout << MyTmeplate( stdafx.h ) // ok, print "D:/Template/MyApp/stdafx.h"
}
How to include files in "D:/Template/MyApp/" if I don't copy them to my own project directorie?
solution like the macro doesn't work perhaps #include instruction doesn't accept another '#' in its statement.
Could someone help me, thanks in advance!

I recommend you have a look at Token Concatenation[^]. That explains how to define and use a C macro to concatenate tokens.
|
|
|
|
|
Considering you're using stdafx.h, I assume you are using Visual Studio? Why not just add the include directory to Additional Include Directories in the Project Properties dialog, under the C/C++ tab. That way, there's no need for possibly troublesome macro's and makes it easier to maintain.
For other build environments there should be similar options.

Thank you. That's a nice solution.
