To figure out a percentage, take the number of items completed, multiply it by 100, then divide it by the total number of operators to complete. If you don't kmow that, you'll need to lie.

I see you need the answer enough to ask three times, but not enough to create an account......

Anyhow, I do not know the answer, but if it's in a wav FILE then surely you can read the data using iostreams ?

creating an image "transition" in gdi+

I'm writing a slide show screen saver, and I want the images to fade in every 5 seconds. I got the fading part working, it's just that as soon as it finishes drawing it seems to be throwing a WM_ERASEBKGND message(or so i'm guessing), rather than waiting the 5 seconds it is supposed to. Any ideas on how to make this work or another method of getting the desired effect? I am a beginner so I would rather not have to use mfc because that would mean having to do a workaround for it to work with scrnsave.lib.

here is what my onPaint function looks like:

PAINTSTRUCT ps;
HDC hdc;
float alphas[] = {0.2f,0.4f,0.6f,0.8f,1.0f};

hdc = BeginPaint(hwnd, &ps);

Graphics graphics(hdc);

...code that gets "filename" is irrelevant so i didnt include it...

Image image(filename);

int x = (GetSystemMetrics(SM_CXSCREEN) / 2) - (image.GetWidth() / 2);
int y = (GetSystemMetrics(SM_CYSCREEN) / 2) - (image.GetHeight() / 2);

ImageAttributes imageAtt;

int iWidth = image.GetWidth();
int iHeight = image.GetHeight();

for(int i=0;i

for loop was cut off in first post

el_robert9-Jul-02 17:53

this is what the for loop looks like:

ColorMatrix colorMatrix = {1.0f, 0.0f, 0.0f, 0.0f, 0.0f,
0.0f, 1.0f, 0.0f, 0.0f, 0.0f,
0.0f, 0.0f, 1.0f, 0.0f, 0.0f,
0.0f, 0.0f, 0.0f, alphas[i], 0.0f,
0.0f, 0.0f, 0.0f, 0.0f, 1.0f};

imageAtt.SetColorMatrix(&colorMatrix, ColorMatrixFlagsDefault, ColorAdjustTypeBitmap);

graphics.DrawImage(&image,Rect(x,y,iWidth,iHeight),0,0,iWidth,iHeight,UnitPixel,&imageAtt);
}

How can ISAPI_Filter call the functions of Soap_Server?

ansoe9-Jul-02 17:19

Hi All,

I have a problem regarding SOAP & ISAPI_Filter.

Now, I'm trying to write an ISAPI Filter(Dll), I'd like to call the function of Soap_Server(DLL) via ---.WDSL.
But my ISAPI Filter can't CONNECT to Soap_Server. My Soap_Server is for some data manipulation, using MS SOAP Toolkit 2.0 & VC++ 6 . I can call it's functions from other Soap_Client programs(MFC/VB exe). But my ISAPI Filter can't call.

So, How can ISAPI_Filter call the functions of Soap_Server?

Anyone have the sample code for that?
Any article about that?

The following Connect() function of ISAPI Filter can't CONNECT to my Soap_Server

bool CPlugIn_IIS5Filter::Connect()
{
HRESULT hr;

CString NewWSDL="http://MyWebServer/SoapSvr/MyDBSOAP.WSDL";
if(m_WSDLConnected != NewWSDL)
{
if (m_pSoapClient != NULL) m_pSoapClient.Release();
hr = m_pSoapClient.CreateInstance(__uuidof(SoapClient));
if(FAILED(hr))
{
// DisplayHResult(_T("Cannot create SoapClient."), hr);
return false;
}
try
{
m_pSoapClient->mssoapinit((LPCTSTR)NewWSDL, _T(""), _T(""), _T(""));
}
catch(_com_error err)
{
// DisplayFault(_T("Cannot initialize SoapClient. "));
return false;
}
m_WSDLConnected = NewWSDL;
}
return true;
}

If you have any info, pls forward to me.
Any other way to connect Soap_Server?

Thanks and best regards

How much memory is used?

Using SHFileOperation.

David Fleming9-Jul-02 16:58

I keep getting an error message telling me that the file cannot be found UNLESS I hard-code the name of the file to work on (in this case delete).

Here's the code:

SHFILEOPSTRUCT fileOp;
CString sSrc; //this is actually declared and set earlier
fileOp.hwnd = this->m_hWnd;
sSrc = pItem->sCol4; //pointer to a STRUCT containing CStrings
fileOp.pFrom = (LPCSTR)sSrc; //Source path+name
fileOp.pTo = "\0"; //Unhandled exception if I don't set this
fileOp.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
fileOp.wFunc = FO_DELETE;
int iRes = SHFileOperation(&fileOp);

It seems apparent that the problem is in the conversion from the CString to LPCSTR for fileOp.pFrom. It works fine if I replace the line "fileOp.pFrom...." with

fileOp.pFrom = "C:\\Dummy.txt";

The strings look correct in the debugger window, so I'm at a loss here.

I've tried various different castings and even tried using sSrc.GetBuffer(n) where n is various different values. None of those things seems to make a difference.

So what's the snag? Any suggestions?

pFrom must be a double-null-terminated string. It is actually the Win32 version of a string list - one null-terminated string after the other, with two nulls to mark the end. The version where you set pFrom to a string literal just happens to work, even though the correct literal is "c:\\dummy.txt\0".
You'll need to set up a character buffer (not a CString because CString does not handle embedded nulls) and use that for pTo.

I had noticed in the documentation that .pFrom (and .pTo) had to be double-null terminated, but I did not realize that CStrings would not handle the nulls. Thanks.

Oh, BTW, it worked with "c:\\Dummy.txt", "c:\\Dummy.txt\0", and "c:\\Dummy.txt\0\0".

However, I confess that I'm lame where string manipulation is concerned. I've fiddled with it and still can't get it to work. Here's what I've got:

fileOp.hwnd = this->m_hWnd;
sSrc = pItem->sCol4;
char szSrc[255]; //my buffer for the string
strcpy(szSrc, (LPCTSTR)sSrc); //this works fine
int iSize = strlen(szSrc); //len appears OK
strcat(szSrc, "\0\0"); //append double nulls
iSize = strlen(szSrc); //debugger says len is same (?)
fileOp.pFrom = szSrc;
fileOp.pTo = "\0\0";
fileOp.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
fileOp.wFunc = FO_DELETE;
SHFileOperation(&fileOp);

Ugh! I'm clearly missing something rather fundamental.

Thanks.

strcat(szSrc, "\0\0"); has no effect. Watch the szSrc array in the memory watch window and you'll see. None of the C string functions work with embedded nulls, because the first null ends the string. What I do is zero-fill the array so no matter how long the actual file name is, there will be zeros after it.

char szSrc[MAX_PATH+1] = {0};

Yeah, I noticed that the strcat(szSrc, "\0\0") did nothing.

Thanks for the suggestion (zero filling the array) -- it worked like a charm.

I just don't think I would have ever thought of it.

BTW, I've enjoyed your articles. Keep up the excellent work and thanks a bunch.
