(Forgive me for posting this in the VC++ forum)
I'm trying to get command prompt autocompletion to work on my W2KSP4 box. Anyone know the registry setting? The entries I've found while Googling don't seem to work. Thanks,

I am working on a project of BHO and I need to make a PropertySheet dialog box pop up when I click on an item in the context menu. The property sheet is from the BHO. The problem is sometimes the PropertySheet is displayed under the current IE window and the user cannot see it. I know what caused the problem. It is because there is one BHO for each IE window. But when a property sheet is called, the program just use PostMessage to send out a message, and the first BHO that gets it will display the property sheet. That is why sometimes the property sheet cannot be seen. How do I solve this problem?
I tried to use SetWindowPos(NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE) in the property’s initialization function. But it doesn’t work. I also tried to add SetForegroundWindow(); before that. There is still something wrong with it. First, it will make the IE window that the BHO hooked to become the window on focus and make the current IE window hide; Second, it only works on the IE windows from the same thread(The new window is generated from current old window by clicking on File->new->Window). It doesn’t work when the IE windows are on different thread, for exampe, generated by clicking on the blue “e”.
Please help. Thanks a lot in advance

I am not familiar with BHO but did you try wndTop as the first parameter to SetWindowPos() instead of NULL?

Can somebody please enlighten me on the topic of Multicasting and UDP?  I am trying to build a simple chat program, but the problem is that I will need to load one socket per client, so there will be a very big number of connections and I don't want that. The fact is that I heared that Multicasting can help a lot. How can I find out IPs of computer on a LAN and send messages all around?
Thank you lot in advance !

There is some good article about multicasting here.
(Simply type multicasting and you will get them all.)
A good one would be:

Alright. I'm stepping through my code in Visual Studio.NET and I notice in the "Autos" window variable values turn red. I assume this happens to show that a variable value is being modified or was just modified. But I'm not sure. Could somebody explain?
Thanks in advance.

|

Yes u are rite the red variables indicate that they were changed during the last execution of line or lines(if you have set a breakpoint ahead and pressed f5)

Ah, Good. Thank you very much.

In vc6 if I do pow(2,-23) I get the correct answer of 0.00000011920928955078125. In vc71, the same code returns 0. From stepping into the newly templatized pow I see that I can make this work by using 2.0 or casting to a float or double, but this just seems wrong....especially since the method returns a double.
Anyone know if this has been reported as a bug yet?..or how to report if not??
|

Hmmm. That sounds like a templated or overloaded version is being invoked, rather than a "bug" per se, particularly if you're casting.
Does pow(2,-23.0) give you 0 or 1.19e-7 ?

You are passing integers into the function. It worked before because there wasn't an integer version of pow and thus it was forced to use the double version.
There isn't a bug in VC7.1. Fix your code to call the routine properly so it knows you want the double or float version of pow.
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

Integer version or not, the function always returns a double. The code shouldn't have to "know". Whether I pass integers or floats, the correct answer is never 0.
|
|
|
|
|
No the integer version returns an integer that is then automatically casted to a double. With integers only the correct answer is 0.

Hi All,
I have Created a Font using the function:
CreateFont()method.
I want to get the width of the font here for a particular purpose,
So Iam creating a font first with the "CreateFont" function & giving '0' in the width parameter as I dont know the width of the font.
Then I get The font metrics of this font & from it I create a Logfont structute editing the width part.
Now I create the font again with the width .
Everything worked fine until I got into a problem:
I used the "SetWorldTransform" for scaling.Now When I scale the text with a particular font,the scaling is not happening in the horizontal direction(ie: widthwise).
I would like to have the scaling widthwise as well.
Could anyone Help.....
Thanks in Advance..
font.CreateFont(-height,0,rotVal.x ,rotVal.y,style,FALSE,FALSE,0,ANSI_CHARSET,
OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_SWISS,
reinterpret_cast<const unsigned="" short*="">(facename.c_str()));
TEXTMETRIC fontMetric;
m_deviceContext->GetTextMetrics(&fontMetric);
double averageCharWidth =(fontMetric.tmAveCharWidth);
//LogFont Structure
LOGFONT lf;
memset(&lf,0,sizeof(LOGFONT));
font.GetLogFont(&lf);
lf.lfWidth=(averageCharWidth/1.5)*ratio;
//Deleting the fontObject & Creating a New Font.
font.DeleteObject();
font.CreateFontIndirect(&lf);
CFont * pOldFont = m_deviceContext->SelectObject(&font);
The xForm structure is as follows:
XFORM xForm;
xForm.eM11 = 0.01 * m_iZoomFactor;
xForm.eM21 = 0;
xForm.eDx = 0;
xForm.eM12 = 0;
xForm.eM22 = 0.01 * m_iZoomFactor;
xForm.eDy = 0;
SetWorldTransform(pDC->GetSafeHdc(), &xForm);

I'd like to copy the content of a Flexgrid (MS FlexGrid Control version 6.0)to a Word or Excel document. I tried "InvokeHelper(0x37, DISPATCH_METHOD, VT_EMPTY, NULL, NULL);" hoping it would copy a picture to the clipboard but it doesn't.
Ideally, I would like to copy not a picture but the actual data as a table to Excel.
Many thanks in advance for your help.

Actually I am doing a project on face detection
Now i have got the output coordinates of facial features but there are too many of them and i need only a few of them to do analysis so as to achieve face expression detection.
So will the coordinates selected, like x,y (12,23)for neutral expression I want to compare will another x,y (45,76). If if it satisfy the happy criteria, then output will be happy
So how should I link two programmes together?
The first programme output a list of coordinates while the want I am doing will get some valuse and output the expression
i do hope someone will help me

I want to make use of the output of the first programme and then use it to analysis. I am now writing the second programme. The output of the first programme, i will have to store it in some datasheet and then use some of the values for the second programme. Can the programme auto create this datasheet that stores the values in specific places aiting for call out?
U understand what i saying?
Thx alot

i hope i got that right: you want to save some data of program 1 and load it later on into program 2? if so you could use GetPrivateProfileString() & WritePrivateProfileString() to load & save data in .ini files
hope this helps
Я люблю русский язикь!
|
|

|

So with this, i use GetPrivateProfileString() to get the values i want then WritePrivateProfileString() to load it to the second programme. When i use the function get, where does the programme get the values from and will i be able to select the values i wan?
thx

char lpBuffer[256];
GetPrivateProfileString(
"MySection", // LPCTSTR lpAppName
"MyKey1", // LPCTSTR lpKeyName
"0", // LPCTSTR lpDefault - in case file does not exist this is default
lpBuffer, // LPCTSTR lpReturnedString
256, // DWORD nSize
"File.ini" // LPCTSTR lpFileName
);
WritePrivateProfileString(
"MySection", // LPCTSTR lpAppName
"MyKey1", // LPCTSTR lpKeyName
"0", // LPCTSTR lpString - whatever you want to save
"File.ini" // LPCTSTR lpFileName
);
you don't have to create a .ini file; it is created for you in the app's folder.
make sure both programs refer to the same .ini file.

I have array of R,G,B values of some bitmap.
How to display this in my dialog box ?
I've tried this, but this does not display anything :
m_bitmap.CreateBitmap(m_imgWidth,m_imgHeight,1,24,m_imgData);
CClientDC dc(this);
CDC bmDC;
bmDC.CreateCompatibleDC(&dc);
CBitmap *pOldbmp = bmDC.SelectObject(&m_bitmap);
dc.BitBlt(0,0,m_imgWidth,m_imgHeight,&bmDC,0,0,SRCCOPY);
What am I doing wrong ?

(It seems that SelectObject() fails, because it returns NULL)

I have recently followed creating the webbrowser control inside a standard C application window from the article: http://www.codeguru.com/ieprogram/cwebpage.html
I am stuck currently in the land of C.
What i want to acheive is creating standard win32 listbox, button, edit controls on top of the browser control. - Thus benefiting from all the nice to have's with html but running the important stuff from win32.
I have been able to create a button within the rgn of the browser control but 1: It is inactive (probably because it is just a transparent region of the browser control that has not been painted yet)
2: As soon as the browser control gets redraw in that area, it dissappears.
I know many applications use the edges of the client to add the win32 controls but i need it to at least appear as if it's all the same.
I have thought of creating multiple browser controls around my standard controls but my previous experience with the browser control has
I have struggled in vain with trying to set regions of the webbrowser control to transparent + creating the controls with TOPMOST priority.
Your help would be very much appreciated and my final endeavours will be posted back to this site.
Thanks
Carl
