Re: Setting Environment Variables

26-Jul-08 5:57

Through the control panel.

Programmatically, SetEnvironmentVariable() for the current process, or
for the system (from the docs):

"Calling SetEnvironmentVariable has no effect on the system
environment variables. The user can add or modify system environment
variables using the Control Panel. To programmatically add or
modify system environment variables, add them to the
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment
registry key, then broadcast a WM_SETTINGCHANGE message with lParam set to the
string "Environment". This allows applications, such as the shell, to pick
up your updates."

Hi Mark,

Hmmm. The yes or no is in the key! What I'm realy looking for is to enter somehow One string (under vista) into the system via a user session which will be visible to all users. Somewhat naive, I thought for one moment that the Old Fasioned Environment might have been a way in. Evidently it is not.

Thanks, for showing me the wrong path anyways.

There are some concepts in Excel: workbooks, workbook, worksheets, worksheet.

hi please ,can you show me an alternative for StrToInt64Ex()
StrToInt64Ex() works fine for me but it requires IE 6.0
i need an alternative to it which has no additional dependencies

simply i want to convert :
a hex value in any kind of string form "0x090f8g87" to long or similar 243354354

thank you

Can you use the CRT?

If so, see

String to Numeric Value Functions[^]

Although, the CRT is more of a dependency than calling the shell API StrToInt64Ex() Smile | :)

How to compile this project [modified]

Sorry for this long post

I want to compile this whole project (see link below)
http://www.codeproject.com/KB/cpp/loggerservice.aspx[^]

While building the loggertest_src.zip solution I get it to compile but I got three warnings.

The following is the log for the loggertest_src.zip solution
In it the log says WINVER not defined. How to define it for Windows XP, it says defaulting to VISTA, but I'm running XP. And there are three warnings.

Now how to compile the loggerclient_src.zip, all it contains are header files and .cpp files. Should I create a new project and import all the files and then simply build the it.

And with loggerservice_src.zip, when I opened the .dsw file (VC++ 6 Workspace) I got the offer to convert it to the current C++ project format, so I clicked Yes to All, and after that another window popped up which says "The source control provider associated with this solution could not be found. The projects will be treated as not under source control.

Do you want to permanently remove the source control bindings from the projects?"

I got the option of Yes, No, Help

When I clicked Yes, I got this log

Well, your message is not very well formated: it's impossible to read everything. Don't use the CODE block for messages so large.

In fact, what happens is that there are some warnings due to the new version of the IDE (some functions were deprecated) but the guy from were you downloaded the code specified that all the warnings should be treated as errors. You can simply remove that option by going into the project settings: C/C++ -> General -> Treat Warnings As Errors and specify No.

This should fix the problem. Alternatively, it would be nice to fix the warnings too by looking at the text of the warning and try to understand it. For some of them, it's really not that difficult (when it reads "Consider using _snprintf_s instead", I think it is quite understandable).

I the code was developed with VC6, then there should not be any problem compiling it. But as I already said that you just have to disable the 'Treat Warning As Error' option (read my post once again, I explain where you have to go to disable that option).

EDIT: to open the project properties, click on 'Project' in the menu then '... Properties' (with the dots being your project name). This is for VC2005, I don't know which IDE you are using, but it should be quite similar.

WM_CTLCOLOR..... mess VS WM_PAINT

26-Jul-08 7:19

Yup did it all, but the loggerclient is still remaining ? How to do that ? the source and header files in loggerclient are also in loggertest, and I have compiled loggertest successfully, so is there still need to compile the loggerclient, if so how to do it?

I have general question the various WM_CTLCOLOR mess e.g .STATIC, EDIT etc when you are processing controls for Child controls on a modeless dialog box

Can you do the same processing that you can on a WM_PAINT for a Parent window

for instance setting a font via SelectObject in this case I am thinking of WM_CTLCOLORSTATIC

Just trying to get an overall picture

Mark Salsbery25-Jul-08 7:06

25-Jul-08 7:06

I'm not sure it will work there. The docs only mention changing colors.

You can set the font for a control with WM_SETFONT. Even if it works in
a WM_CTLCOLORSTATIC handler, there's no need to do it there.

Call WM_SETFONT when you initialise your dialog (in WM_INITDIALOG); the control will remember it. Delete your HFONT only after the dialog goes away; the control holds a reference to it.

What then would be the difference between the 5 I think its WM_CTLCOLOREDIT ... STATIC

and the WM_CTLCOLOR (HI_WORD)(Lparam) CTLCOLOR_STATIC, EDIT, BTN

Do they all do/expect the same processing

Mark Salsbery25-Jul-08 12:19

25-Jul-08 12:19

The functionality is the same, but WM_CTLCOLOR is a leftover from 16-bit
Windows.

And it looks like there's 6 of them Smile | :)
