Check if this code is of any help :-
CString szCurrentDirectory;<br />
{<br />
CString csPath;<br />
<br />
<br />
::GetModuleFileName(NULL,csPath.GetBuffer(MAX_PATH),MAX_PATH);<br />
<br />
csPath.ReleaseBuffer();<br />
<br />
szCurrentDirectory=csPath.Left(csPath.ReverseFind('\\'));<br />
<br />
}

Hi all
Will I am using GDI+ to manipulate images.
I am having this strange behaviour with Bitmap::Clone() function.
When I create a Clone from an Image object, and then try to LockBits for the cloned image, I get invalid pointer.
I did a workarround for this:
Bitmap* p_new_image = new Bitmap(p_src_image->GetWidth(),p_src_image->GetHeight(),p_src_image->GetPixlFormat());
Graphics* p_graphics = Graphics::FromImage(p_new_image);
p_graphics->DrawImage(p_src_image,0,0);
delete p_graphics;
will this code is working with LockBits very fine.
The documentation for the clone function is not clear, is this a bug in the Clone function, or I didnt understad the Clone function will?
Regards

Hi guys,
i've implemented an manifest file to my app with following info:
---[cut here]---
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><br />
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"><br />
<assemblyIdentity<br />
version="1.0.0.0"<br />
processorArchitecture="X86"<br />
name="SETUP.EXE"<br />
type="win32"<br />
/><br />
<description>APPLICATIONNAME</description><br />
<dependency><br />
<dependentAssembly><br />
<assemblyIdentity<br />
type="win32"<br />
name="Microsoft.Windows.Common-Controls"<br />
version="6.0.0.0"<br />
processorArchitecture="X86"<br />
publicKeyToken="6595b64144ccf1df"<br />
language="*"<br />
/><br />
</dependentAssembly><br />
</dependency><br />
</assembly>
Since then, my listview doesn't accept item background colours i apply using:
if(lplvcd->nmcd.lItemlParam==1){
lplvcd->clrText = RGB(0,0,0);<br />
lplvcd->clrTextBk = RGB(240,240,255);<br />
}<br />
When i remove manifest, all looks okay, but when i apply it again - colours are missing.
Any idea ?
Regards,Paul.

I have both VC++ 6.0 and VC++ 7.1, and I notice that my 7.1 version has icons for source control that indicates when a file is locked by another user VS locked by the current user.
Where as VC++ 6.0 only has an icon showing it's locked.
See following screen shot:
http://code.axter.com/SCC_for_vc71_and_vc60.JPG
I'm developing an SCC AddOn for VC++, and I want to know if there is any way of adding the blue lock icon to VC++ 6.0, and if so, how.
I tried using Spy++ to find the tree window handle, but didn't have much luck.
I appreciate any leads to help solve this.
Thanks

wrong. these error happened when trying to link the compiled object files of your project.
sebinfrancis wrote:

select one error in the output window where you quoted this, and puch F1... msdn exist for that...
ok, now, what does the error say ?
let's take the first one :
MP3PLAYERDlg.obj :
error LNK2001:
unresolved external symbol "public: class CBasePin * __thiscall CAsyncReader::GetPin(int)"
the linker says that there is a call to the member function CAsyncReader::GetPin(int) into MP3PlayerDlg.obj (see the corresponding .cpp file), but it doesn't know such a function...
and all the errors you get are of this style...
so, did you well #include the headers ?

Hi there
I need to find a way to reliably detect the date and time of the last startup/reboot of Windows.
I have found some information that could be used on Win95, Win98, and WinME platforms (checking the date and time of the registry backup files c:\windows\system.da0 and c:\windows\user.da0, or the last accessed time of autoexec.bat).
Is there a similar method that works on all versions of Windows? If not, is there a similar method on WinNT, Win2k, and WinXP?
Cheers,
Johan

Johan - I'm pretty sure for WinNT, Win2k, WinXP you can query a PDH (Performance Data Helper) Value called 'System Up Time', but I dont have any code here to prove it

![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) Yes there is a gettickcount() function to calculate the uptime
i think it will return the values in seconds. you can calculate it
accordingly.
any further details refer WMI classes in msdn

Milliseconds actually.
This will be the simplist, most universal approach, though the DWORD counter will rollover every 49.7 days, so you'll have to take that into account.

QueryPerformanceCounter and QueryPerformanceFrequency will help. They have a roll-over that is much much more than 49 days.
Don't try it, just do it!

Thank you everyone for your kind responses
You do however not answer my question, I want to detect the date and time of the last startup/reboot, not the time elapsed since then.
Maybe I should have been a bit more informative, I am adding this code as part of a software protection system, and I want to find a way to detect of the system time has been changed to a valid day within their evaluation period.
On the old Win architecture, this works perfectly by checking the files mentioned above. But how can this be achieved on the NT platform?

I need to write a class which manipulates char in Unicode form.
So i need materials related to implementation techniques for unicode using c++ class..
thanx in advance

How about using std::wstring instead?

No NO my question is
i need to write a class which deals with unicode...
If i store a particular char in the class, using some functions i should be
able to say its catagoreis.............
there are nearly 30-40 catagories....
so i need to catagory the char which is stored in my class...?
any guess?

Hello...
I am trying to make a WYSIWYG editor and for that I am using the MSHTML control (in a win32 application).
Well it works fine you can set properties of the text with the build in functions...
Than I get a text range (with IHTMLTxtRange) (i can get the text range with no problem) and modify it using pasteHTML (i am doing that to apply font properties...) (i can do what I want but maybe there is some problem here).
Well after that I cannot change anything with the built in functions... But my functions continue working...
I am thinking about the selection range... Do I have to select the whole document and out it in a range in order to edit it with the built in functions?
What may be the problem?
Thank you very much in advance for your answers...
Well... I am a beginner ...

My question is related to client/server programming;
Can we communicate between client and server which have benn developed using different technologies, e.g. client using a Winsock control and server using CSocket class, or say raw winsock apis, MFC etc.
What about different plateforms
|
|
|
|
|
Normal winsock and raw winsock can work together...
CSocket should work also...
Well... I am a beginner ...

Hello
I have few questions related to MFC.
1. I have added a tree control and a rich edit control in Dialog based application. My aim is that when i click an item in tree control, text is displayed in rich edit control. I have modified the code of NM_CLICK event handler for a tree control. So that when i click an item in tree control, an operation is perfomed. But i have to click that item two or three times to display text in rich edit control where as text should be displayed in rich edit control by clicking item just one time. Can anyone please tell me where i am doing mistake? I have given my code below
void CTreeDlg::OnClickTree(NMHDR* pNMHDR, LRESULT* pResult)
{
CTreeCtrl* pCtrl = (CTreeCtrl*) GetDlgItem(IDC_TREE);
HTREEITEM hCurSel = pCtrl->GetSelectedItem();
if (pCtrl->GetItemText(hCurSel) == "Aqueel") // if i clicked on Aqueel in tree control
{
// displaying contents of a file in rich edit
CFile cFile(TEXT("myfile.rtf"), CFile::modeRead);
EDITSTREAM strm;
strm.dwCookie = (DWORD) &cFile;
strm.pfnCallback = WriteEditData;
m_Info.StreamIn(SF_RTF, strm);
}
*pResult = 0;
}
2. How can i clear the contents of a rich edit control.
3. After i have included a .rtf file as a resourse in my project, how can i display it in rich edit control.
Please help me
Thank you.
