Retrieve the string from the variant and then write it like you desire in the html.

are there the functions that convert the datetime format to string format?

Try to retrieve the VT_BSTR part of the VARIANT instead of the VT_DATE.

Hi,
I am dealing with Excel Automation. I get most things working, but now I have a very strange behaviour:
I created a big macro, which creates a pivot table from a normal table, and then makes a chart out of it.
When I run the macro from the excel file, everything works!
But, when I run the macro through a c++ program, it crashes.
Here my C++ code:
hr = CreateObject(OLESTR("Excel.Application"), &pdispApplication);
V_VT(&v) = VT_BOOL;
V_BOOL(&v) = TRUE;
hr = Invoke(pdispApplication, DISPATCH_PROPERTYPUT, NULL, NULL, NULL,
OLESTR("Visible"), TEXT("v"), v);
hr = Invoke(pdispApplication, DISPATCH_PROPERTYGET, &vRet, NULL, NULL,
OLESTR("WorkBooks"), NULL);
pdispWorkbook = V_DISPATCH(&vRet);
V_VT(&v) = VT_BSTR;
V_BSTR(&v) = SysAllocString(OLESTR("C:\\Dokumente und Einstellungen\\geh\\Desktop\\Excel Tests\\Test02.xls"));
hr = Invoke(pdispWorkbook, DISPATCH_METHOD, &vRet, NULL, NULL,
OLESTR("Open"), TEXT("v"), v);
V_VT(&v) = VT_BSTR;
V_BSTR(&v) = SysAllocString(OLESTR("Test02.xls!Chart"));
hr = Invoke(pdispApplication, DISPATCH_METHOD, &vRet, NULL, NULL,
OLESTR("Run"), TEXT("v"), v);
What it does:
It creates the pivot table, and creates a new chart. But when trying to set the XValue or Value from a new series, it says:
"The XValue-Propertie cant be set"
Here the code snippet from the macro:
Sheets.Add
Charts.Add
ActiveChart.ApplyCustomType ChartType:=xlBuiltIn, TypeName:= _
"Linie - Säule auf zwei Achsen"
ActiveChart.SetSourceData Source:=Sheets("Tabelle3").Range("A1")
Set st = ActiveChart.SeriesCollection.NewSeries
With st
.Name = "=""Anz. KLEs am Platz"""
.XValues = "=Tabelle2!R4C3:R4C57"
.Values = Values
End With
As I said, if run it directly from the xls file, it works!
And yes, the table "Tabelle2" is there, and opened.
If I put a "stop" before it, so that I can trace it, it looks totally equal!
Wheres my problem?
EDIT: I just solved it by using .XValues = Worksheets("Tabelle2").Range("A4:BP4")
But I still would like to know where my problem was!

Hello All
I am using List control on my Form View (VC 6.0 on Windows 2000). I have derived my own class from CListCtrl and overwritten "OnCustomDraw" to draw my own List Control. I have placed the control on top of the Tab Control. When I switch from my application to another application and come back, repainting is not happening properly. I am seeing the tab control and the list control is not visible. After some time it appears automatically or if i go to some other tab and come back it appears.
I have not overloaded OnDraw in my View Class.If I use CListCtrl without using my own class then repainting happens properly.
As a solution for above problem I overloaed OnDraw in my view class and i painted the list controls.
<br />
void CMyView::OnDraw(CDC* pDC) <br />
{<br />
if (m_oTabCtrl.GetCurSel () == 0) {<br />
m_oMyListCtrl1.Invalidate ();<br />
} else {<br />
m_oMyListCtrl2.Invalidate ();<br />
}<br />
}<br />
After this I am not getting any painting problem.
Please let me know what was the cause for above problem and whether is there any better solution than this?
Thanks for your time

I have a dll which is getting instantiated from one virtual directory. And inside the dll I'm calling the following functions.
HANDLE hEventSource = RegisterEventSource(NULL, _T("TrxDax") );
if (hEventSource != NULL)
{
..
int b = ReportEvent(hEventSource, EVENTLOG_ERROR_TYPE, 0, 0x00000001L, NULL, 1, 0, (LPCTSTR*) &lpStrings[0], NULL);
...
}
1. Actually the RegisterEventSource() call is failing if the call is made from virtual dir. in Win2003. GetLastError() is returning error value(5) meaning Access denied for the call.
2. But the same thing is working on earlier versions(win2000,XP..).
3. And when the above code is used in a .exe file(simple exe file), then it's working in Win2003. Meaning..(error is reported in eventlog).
4. So, Does the enhanced security in 2003 is blocking the call when it's instantiated through virtual dir.?
Is it clear? or do let me know if some more input is needed..
Thanks

Hi,
I need to remove a section of text from a CRichEditControl, but also store all of the formatting data associated with it- so that I can re-insert it later on.
Does anyone know of a way to use the underlying clipboard operations to do this? i.e instead of removing text, it is cut (into some storage location - not the clipboard!) and then when the text needs to be replaced, it is pasted from that location.
if not, is there some simple method for storing all of the formatting data associated with a range of text? It's worth noting that the CHARFROMAT and PARAFORMAT will be different for different parts of the text.
tricky one, eh?
Thanks in advance,
Dave

Hello guys!I've been coding MFC apps for 3 months now,and i recently encountered the situation below:
I have a Dialog window (class CControlPanelDlg) and a picture control object called m_pcTest(of type CStatic).I have created a structure called "Bitmap" that contains the following array : CBitmap Icon[4].I've created 4 bitmap images and loaded them into Icon(Using LoadBitmap(IDB_IMAGE_ID) method).I want to change the image that m_pcTest shows each time i click a Button within the window(using m_pcTest.SetBitmap(Bitmap.Icon[0])).So far so good.The image changes.Then i created a thread,that it's thread function calls another function located inside CControlPanelDlg.cpp,the same function i use to change the image shown in m_pcTest every once i click the button.While in Debug mode,i noticed that when the program jumps inside the function that change images (m_pcTest.SetBitmap(Bitmap.Icon[0])),the variable m_pcTest has the following value:
m_pcTest={CStatic hWnd=???}. When the program passes the line that contains the breakpoint,it throws a nasty Access Violation!I tried calling tha function from within the thread function with different ways,like:
((CControlPanelDlg*)AfxGetApp()->m_pActiveWnd)->ChangeImage();
p_ControlPanelDlg ->ChangeImage();
(p_ControlPanelDlg ---> external pointer to CControlPanelDlg dialog class)
The variable m_pcTest is public.Am i doing something wrong?Did i forget to declare something?Or i declared it in the wrong way?Please help.I know i'm new to MFC,and you probably going to ask yourself "why this young lad bothers himself with threads so early"? The answer is i'm in love with MFC and i've learned so much within those 3 months(mostly Serial Communication,Database projects) and i needed to learn how to change bitmaps while other code was executing.I tried to do this with timers but as long as my code enters a loop,ChangeImage()could not be called until code execution continued beyond the loop.I tried UpdateData(FALSE)from inside the loop,but nothing happend.So i needed a co-process,a thread.I would appreciate it if someone of you code gurus out there could help.Thank GOD that "The Code Project" exists as my homepage...

Instead of directly calling ChangeImage from your worker thread, you need to make the CDialog's m_hWnd available to the thread (when you create it) and then use it to post a private message from the worker thread back to the dialog. Use a handler for that message in the CDialog to call ChangeImage.
Hope that helps,

char v1[12]= "CodeProject";
char v2[5];
strncpy(v2,v1,sizeof(v2));
AfxMessageBox(v2);
Now what will u get, don't test it in ur IDE.. just hav a luk n tell..
answer this , i'll tell u what i actually need..
Thanks n regards,

here again, i see you don't take care to the trailing null character...
you should have written
strncpy(v2, v1, sizeof(v2)-1);
v2[sizeof(v2) - 1] = '\0';
this way, it will display Code
the other way to use strcpy() and strncpy() properly is to use pure pointers variables :
char v[12] = "CodeProject";
char* pc = NULL;
strcpy(pc, v);

I guess, you meant v2[sizeof(v2) - 1] = '\0'; ?

Doesn't this lead to a runtime error? Here you try to copy string v to the address NULL...

To get "Code" you need a terminating NULL:
char v1[12]= "CodeProject";
char v2[5];
strncpy(v2, v1, sizeof(v2) - 1);
v2[sizeof(v2) - 1] = 0;

Hello,
I try to write a program that uses http tunneling. But behind a proxy it won't work. Of course i can get the proxy settings from registry but the username and passowrd aren't stored, so if i want to connect i need to know the username and password. How can i get them?
One more information: the program is in vc++ and the iexplorer must start before it. So the user is authenticated.

your program will have to ask for those 2 infos to the user to store them... (that's what happens for example when you configure other programs for a proxy connection...
