Is it possible to write to the .ini file from a .bat file?
Here's what I'm trying to do:
I have .bat that is supposed to make the user's life easy by installing our software using a base directory that the user specifies. So the user would execute "installProd.bat C:\user_area" (or Whatever Disk>:\where ever). The .bat creates the directory specifed (as well as others below it) places our C++ executables and our supporting files (like any input data files or help files, etc) into the dirs.
Now I'm hoping to write to the .ini file from within the .bat so I can put the user defined base directory into the .ini. Then when the C++ executables run, the executables can access the .ini file for the base directory path (using GetPrivateProfileSettings or GetProfileString etc).
Is it possible? Or am I going down the wrong path for this? ANy suggestions and guidance is much appreciated!
Thanks,

You can use echo .For instance, the following commands
echo>parms.ini [general]
echo>>parms.ini key=value create an .INI file like this
[general]
key=value Note that a single > means "create new file" and >> means "append". Hope this helps.

why not use an installer ?
InnoSetup (http://www.jrsoftware.org/isinfo.php) provides a simple tool for creating setup's. It has also builtin support for writing in .ini file.
The Tool is free available and well supported
If you still want to handle the stuff with a batch script:
append your stuff at the end of that ini-file via
...
echo [section] >> myIniFile.ini
echo myKey=%1 >> myIniFile.ini
...

Thanks both of you for your responses. I completely overlooked the obvious.
BTW, the installer suggestion is a great one, but my company often refuses to use anyone else's software but their own (the wheel has been reinvented more times than I can count
Thank you both so much for your responses!

After working on project for several months I started getting assertion failure at winocc - GetExStyle. I have been "solving" this problem by regressing to last working version of the project. But now I am stuck, it fails every time I add new stuff. I need to fix this. Rumor has it it has to do with OLE, but I have been unable to find anything on the web.
Here is the Output message :
...
Warning: Window creation failed: GetLastError returns 0x0000057F
Warning: failed to create CFrameWnd.
...
How can I get to this "last error" ?
Thanks for your help.

Check out line 570 of winfrm.cpp. CreateEx() returns ERROR_CANNOT_FIND_WND_CLASS if the class name specified is invalid. Set a breakpoint on that line and note the value of lpszClassName . Having that might help to narrow down the problem.

Thanks for your suggestion.
Found the cause , now what?
How is it possible to run wrong process?
My code seems to be failing when I modify/ add to my dependent library!
It works OK when I work on my main project only
Here is what is happenning:
MFC runs CWnd::CalcWindowRect(LPRECT lpClientRect, UINT nAdjustType)
instead off PreCreateWindow(cs)! per following sinipet:
LPCTSTR CFrameWnd::GetIconWndClass(DWORD dwDefaultStyle, UINT nIDResource)
...
CREATESTRUCT cs;
memset(&cs, 0, sizeof(CREATESTRUCT));
cs.style = dwDefaultStyle;
this call is not executed !
PreCreateWindow(cs);
// will fill lpszClassName with default WNDCLASS name
// ignore instance handle from PreCreateWindow.
...
So, the cs is never filled out and the file name is missing!
void CWnd::CalcWindowRect(LPRECT lpClientRect, UINT nAdjustType)
{
assertion fails here, as it should, because of wrong/ no data in cs
DWORD dwExStyle = GetExStyle();
if (nAdjustType == 0)
dwExStyle &= ~WS_EX_CLIENTEDGE;
::AdjustWindowRectEx(lpClientRect, GetStyle(), FALSE, dwExStyle);
}
WNDCLASS wndcls;

I have a problem with the include files and I am getting an error :
win32.obj : error LNK2019: unresolved external symbol _BltAlpha referenced in function _DD_Init
This is how I have set up the project:
I call the BltAlpha in DD_Init in
win32.c:
#include "stdafx.h"
bool_t DD_Init(win* p)
{
BltAlpha(p,.....
I have declared all my include files in
stdafx.h:
#include "win32.h"
#include "blend.h"
And then I have included stdafx.h in both blend.c and blend.h
blend.c:
#include "stdafx.h"
// The implementation of BltAlpha:
int BltAlpha( win* p,int iDestX, int iDestY, LPRECT lprcSource, int iAlpha, DWORD dwMode )
{ ............
blend.h:
#include "stdafx.h"
//The declaration of BltAlpha:
int BltAlpha( win* p,int iDestX, int iDestY, LPRECT lprcSource, int iAlpha, DWORD dwMode );
So why am i getting this link error, I have really tried to put the header files in different combinations, but with no luck?!
Please is there anyone that can help me with this one before I´m going crazy!?
Thanks, Dani

Hi,
I think that this is a tricky question : try and rename your .c files into .cpp files, and it should solve the problem . Visual adapts the calling convention according to file extensions. You have probably created a C++ project, and tried to insert a c file. A very naive explanation would be: the way the parameters are called with
BltAlpha(p,.....
is the C++ way and the way you declare in in blend.c is compiled as the C calling convention. This is Ok for the compiler, but it cannot be linked.
If you do not want to rename your files, try modify the calling conventions in the settings of your project Project->Settings->C/C++->Category:Code Generation->Calling convention.
But I must admit, this is tricky

As for the header file organisation, this should do it:
stdafx.h:
#include "win32.h"
#include "blend.h"
win32.c:
#include "stdafx.h"
blend.c:
#include "stdafx.h"
~RaGE();

Thanks Rage!!!!!!
Whooooooops! the blend.c was named blend.cpp in my project, did not noticed that !
This have to be a bug in Visual C++ 6.0, because the only options for adding a file is
new->c/c++ header file
or
new->c++ Source file and there is no option for a new c file
This is strange though, anyway thanks Rage

Hi,
I want to replace the hardcoded string by the path in %windir% in the following code
#ifdef WIN32
CHAR CFM_INI_FILE[CFM_NAME_LEN] = "C:\\Winnt\\abc.ini";
#else
CHAR CFM_INI_FILE[CFM_NAME_LEN] = "/Winnt/abc.ini";
#endif
can I do that?
I cannot use GetWindowsDirectory function because this code is in global space in a cpp file.
My understanding is a function can be called only from within a function and not from global space.
Please advice..
P.S. :- this code has to be in global space. If i put it in function and initialize there i have to make changes in over 60 files to make sure it is initialized before it is used.

It is possible to get the value of %windir% with several functions, amongst them
char *getenv( const char *varname );
but from what I understand in your msg, you do not want to use any initialisation, e.g. function call. So I am afraid that the answer to

can I do that?
is : yes, you can, but it will unfortunately not be replaced at runtime with "C:\Winnt".
So, be ready to modify your 60 files

Hi,
Am sorry if the subject looks too long. Didn't know how to explain it better....
Here is my problem. I divide my SDI into 2 columns using dynamic splitter. I associate the left column with some view. Now i want the right column's view to show a dialog resource from one .dll. I could get the dialog resource from the .dll and display it in the right view by getting the resource ID from the dll ( after loading it ofcourse ) and then using the FindResource() and LoadResource(). But the problem is that if i enter something in the dialog resource and then click "Ok", then i expect my handler in the .dll to be called and then retrieve all the configuration parameters that user enters in the dialog resource.
But my handler is not getting called, and obviously because of that, the dll cannot get the parameters entered into the dialog resource.
Is there any way to do this? So that the .dll can contain the dialog resource, and i can embed it in my main exe after loading that dll. And then once user clicks ok on the dialog, the appropriate handlers and data exchange happens inside the .dll, and my main application neednot care about the configuration parameters that the .dll wants...
Thanks & Regards,
Kumar

Hello
I would like to call ImpersonateLoggedOnUser to gain some extra rights for a particular task in my application. For the call I need an impersonation token. To get this I tried the LogonUser function, but I don't have enough privileges. Probably it's the SE_TCB_NAME privilege. If I inspect the results from GetTokenInformation it is true that I don't have that priv and hence cannot enable it.
Does anyone know how to get a proper impersonation token.
I've tried to call CreateProcessWithLogonW to create a dummy process as a different users, and with that process handle I can call OpenProcessToken to get a token to send to ImpersonateLoggedOnUser. This gives the expected result, but it is a verry uggly work around.

are somehow contradictory. If the "different users" you are talking about has enough privileges to make a good token for ImpersonateLoggedOnUser , you should also be able to use it for
LogonUser and hence get the same sufficient privileges ... I think your call to LogonUser must have failed somewhere ...

Consider the following-
DrawText (hdc, "Hello, Windows 95!", -1, &rect,
DT_SINGLELINE | DT_CENTER |DT_VCENTER) ;
Could someone show me some code that would draw each letter in a different color?
While I am grateful for any help you could offer, please just dont reply with something line "just use CDC::SetTextColor...". I know that. My problem is in how best to iterate through each character in the text and assign each letter a different color. I want to see A CODE FRAGMENT.
thanks again.....

|

again ?
a couple of questions ...
Do you know how to iterate through each character ?
Do you know how to compute the size/position of the text ( using CDC::DrawText )
another BIG hint : DT_CALCRECT ...

Thanks for your answer. I know how to iterate. What I don't know is how to format the function call.
Example:
CString _str;
DrawText (hdc, "Hello, Windows 95!", -1, &rect,
DT_SINGLELINE | DT_CENTER |DT_VCENTER) ;
// Can I say something like
//call to iterator
{
DrawText (hdc, "_str[i]", -1, &rect,
DT_SINGLELINE | DT_CENTER |DT_VCENTER) ;
}
|

}
Only if you want _str[i] to show up on the DC.

I'm using the following to read a large text file ( 80+megs ); I need to read individual lines and eventually put them in a vector ( to be processed later )
ifstream file1
std::ifstream file1 ( sFileName.c_str() );
std::string oneString;
while (std::getline( file1, oneString ) )
{
}
this takes around 70 secs.
while using MFC
CStdioFile file( sFileName.c_str() , CFile::typeText|CFile::modeRead );
while (file.ReadString(s) )
{
}
takes around 10 seconds.
Is there a better way ? seems that reading with STL should not take that much more time than with MFC.
Is there a way to do it with some kind of inserter like ( this is very vague ... )
something = std::somefunction( filestream.begin(), filestream.end(), somefunctorToReadALine );
Thanks!!!

hi everyone...
i have this little problem i hope you can help me with.it's as follows:
i'm making a dll that contains a lot of functions..these functions work on both xp and 9x except for one function ((suppose it's fn1)) that works only on xp((this function uses SetLayeredWindowAttributes))...the problem is when building the dll with fn1 and then trying to use a not fn1 function on win9x an error message appears reporting that the dll is not found!!!!after building without fn1 the dll works properly...i want to be able to use the 9x supported function of the dll even if it's built with fn1...
note:there are no problems at all on winxp...
