As mentioned in my answer to your question yesterday, use the regular File API like CreateFile, ReadFile etc

Hi All
I have a problem to Show USB Drive Name and File name.Problen is that when i insert a USB device then Drive Name and file name is show but also show Some dummy line like this
"ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌA". I debug the code.When i change the this line
char chDriveLabel='A'; to char chDriveLabel='B'; then it is working fine.But when i change this line then i have found some problem like when i insert the
first usb device then nothing show and when i insert
more than i device
then it is showing.So Plz help me code is here
BOOL CUSBDlg::FileList()
{
DWORD dwDrives=GetLogicalDrives();
if(0==dwDrives)
{
return FALSE;
}
DWORD dwCount=0;
char chDriveLabel='A';
char szRootpath[5]={0,0,0,0,0};
while(dwDrives !=0)
{
if ((dwDrives & 1) != 0)
{
sprintf(szRootpath,"%c:\\",chDriveLabel);
if(DRIVE_REMOVABLE==GetDriveType(szRootpath))
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
m_ListCountries.AddString(szRootpath);
m_tree.InsertItem(szRootpath);
szRootpath[3]='*';
hFind=FindFirstFile(szRootpath,&FindFileData);
if (INVALID_HANDLE_VALUE == hFind)
{
}
do
{
if (strcmp(FindFileData.cFileName,_T(".")) && strcmp(FindFileData.cFileName,_T("..")))
{
m_ListCountries.AddString(FindFileData.cFileName);
m_tree.InsertItem(FindFileData.cFileName);
}
AfxMessageBox("helloP");
AfxMessageBox(FindFileData.cFileName);
}while (FindNextFile(hFind, &FindFileData) != 0);
FindClose(hFind);
}
}
dwDrives = dwDrives >> 1;
chDriveLabel++;
}
return true;
}

That's a repost.
BTW, as suggested yesterday, why don't you handle the FindFirstFile function failure?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

ok so what i use there in place of FindFirstFile
|

Actually handling FindFirstFile failure means: take an adequate action whenever the function fails (for instance, stop further elaboration and report the user that no file was found). You do nothing in such circumstance.
I'm not suggesting you to use another function.

No one is debating that. The problem is that you are continuing on even if that function fails.

Hi,
I have two functions funx() and funy() in my VC++ application.Could someone suggest me a tool/mechanism as how to find which functions (application flow)are called in between funx() and funy().
I need this urgently.
Thanks in advance.

Im not sure Im understood your question but why you dont use of deugger(F11 or F10/breakpoints)?
|
|
|
|
|
Thank You Hamid.
What I want to know is whether there is any tool that lists the functions called in between funx() and funy()

yes, the DEBUGGER does it ! by showing the call stack.
but you seem to be to lazy to search a bit by yourself...

Normally you can use the debugger.

But that's bothering me. For urgent purposes, I don't know if the debugger will help.

Hello friends,
I've an IE Toolbar with VC 6.0.
I am calling a webservice from the application which result in HTTP 400 i.e "Bad Request".However calling webservice works for the first time successfully but after that whenever I call the webservice it results in "Bad Request".If I close the browser and reopen it will work again for one time only, Can anybody tell me what could be the problem?
vRequest.vt = VT_BSTR;
vRequest.bstrVal = szRequest.AllocSysString();
MSXML::IXMLHttpRequestPtr httpReq( _uuidof(XMLHTTPRequest));
HTTPMethod = _bstr_t("POST");
httpReq->open(HTTPMethod ,SERVER_URL,noAsync,vtMissing,vtMissing);
httpReq->setRequestHeader("Content-Type","application/soap+xml");
HRESULT hr=httpReq->send(vRequest);
if (httpReq->readyState == 4 )
{
if(httpReq->status==200)
{
bsResponse = httpReq->responseText;
}
else
{
_bstr_t strline=httpReq->statusText;
CString strstatus;
strstatus=strline.copy();
MessageBox(strstatus);
}
}
response.Empty();
response=bsResponse.copy();
I parse the response for getting the "true" or "false" value.
I get the correct response for the first time but after that the response is empty and statusText result in "Bad Request".

It seems like you are not closing the connection and trying to reconnect to the service .
