HI~
How to search a substring from LPWSTR?
Also I cannot extract a character like string class
e.g
I cannot do this:
LPWSTR a_string = _T("abcdef")
if (a_string[2] == 'c'){...}
How to extract a character is the string is LPWSTR type?
Thanks

|
|
LPWSTR a_string = _T("abcdef");
if (a_string[2] == (WCHAR)'c'){...}
...Plug & Pray...

Actually the correct syntax is L'c' for wide-char literals. (Your code will work but I didn't want the original poster to get the idea that casts are the solution for string-related stuff.)

LPCTSTR SubString( LPCTSTR lpExpression, // [in] Pointer to a string to extract the substring from
ULONG nStart, // [in] Starting point
LONG nLength = -1 ) // [in] how far to go from the startig point, use -1 to go the end of lpExpression
{
if( nLength < 0 )
nLength = strlen(lpExpression) - nStart;
ULONG nPos = 0;
PTCHAR lpResult = new TCHAR[512];
for( ULONG i = nStart; i < (ULONG)(nStart+nLength); i++ )
{
// put the current char from lpExpression into lpResult
lpResult[nPos++] = lpExpression[i];
}
// add the null byte to lpResult;
lpResult[nPos] = '\0';
// return the substring
return lpResult;

INT_PTR nResponse = dlg.DoModal();
return -1 if when i add a custom control using resource editor.
how can i solve this?
|

Probably the window class for custom control is not registered before DoModal call. Are you trying to call RegisterClass in OnInitDialog?

Hi all
I have a little problem. I am using ADO to connect to a database, I have managed to add records to this db, but when I want them displayed the recordset is empty, what am i doing wrong?
Is it possibly because access 2000 has limitations on the amount of fields you can view?, Is it because ADO has limitations on the record set?, I have even copied working code from another program and still the record set is blank!
Here is the code:
<br />
void CViewRptDlg::OnShowReport()<br />
{m_strConnection = _T("DSN=Report_prg");<br />
m_strCmdText = _T("Select * From R_tbl where MonthName='"+CString(m_strMonth)+"' and WardNumber='"+CString(m_strWard)+"'");<br />
m_pConnection = NULL;<br />
m_pCommand = NULL;<br />
m_pRs = NULL;<br />
m_piADORecordBinding = NULL;<br />
::CoInitialize(NULL);<br />
<br />
try<br />
{<br />
<br />
m_pConnection.CreateInstance(__uuidof(Connection));<br />
m_pCommand.CreateInstance(__uuidof(Command));<br />
m_pRs.CreateInstance(__uuidof(Recordset));<br />
m_pRs->Open(LPCTSTR(m_strCmdText),LPCTSTR(m_strConnection),adOpenDynamic,adLockOptimistic,adCmdUnknown);<br />
if(FAILED(m_pRs->QueryInterface(__uuidof(IADORecordBinding),(LPVOID*)&m_piADORecordBinding)))<br />
_com_issue_error(E_NOINTERFACE);<br />
m_piADORecordBinding->BindToRecordset(&m_rsRecSet);<br />
RefreshBoundData(); <br />
}<br />
catch(_com_error &e)<br />
{<br />
GenerateError(e.Error(),e.Description());<br />
}<br />
<br />
void CViewRptDlg::RefreshBoundData()<br />
{<br />
CCustomRs *pRs = GetRecSet();<br />
<br />
if(adFldOK == pRs->lReportIDStatus)<br />
m_nReportID = pRs->m_nReportID;<br />
else<br />
m_nReportID = 0;<br />
if(adFldOK == pRs->lMonthNameStatus)<br />
m_strMonth = pRs->m_szMonthName;<br />
else<br />
m_strMonth = _T("");<br />
if(adFldOK == pRs->lWardNumberStatus)<br />
m_strWard = pRs->m_szWardNumber;<br />
else<br />
m_strWard = _T("");<br />
UpdateData(0);<br />
}<br />

Can anyone point me to an example of an MFC owner drawn window? (That does NOT use a remake of CDialog class)

Hi,
I just want to add a cool feature to my application: creation of pdf documents from data in a listview control. However, pdf is a binary format, and therefor not as straightforward to create as for example html.
Does anybody know of a free (maybe open-source?) library that works under Visual C++, to create simple pdf files?
Thank you,
Erik

I think PDFlib Lite is free for personal use.
Visit www.pdflib.com and look for PDFlib lite.

Well, I am a newbie programmer.
I need help with a lil project I am making.
Lets say I have this button called increase, when I press this button I want it to add 1 to the variable x, and display the changes.
So under the button "OnIncrease",
I chose and put the command
x++;
Which lets me add 1 to the variable x which is an unsigned long. Once this button is clicked, I want to also make it display in the box called "OnList"
which is a list box.
Can anyone explain simply how to make it say, "You have "x" dollars in your account."
Thanks,
make sure it is simple for me to understand.

CString str;
CString output;
str.Format("%i", x);//make a string from your number
output = "You have \"" + str + "\"dollars in your account.";//make nice ans fluffy string. (\" is a " character in your string)
listbox.Add(output);//add to listbox (could be AddString or something don't know by heart)
hope this helps.

I tried implementing your code and I got errors.
Do you think you can manually explain it?
What did you mean make nice ans fluffy string?
I get these errors -_-
F:\Documents and Settings\Administrator\My Documents\Arun\Code\Tycoon\TycoonDlg.cpp(107) : error C2065: 'listbox' : undeclared identifier
F:\Documents and Settings\Administrator\My Documents\Arun\Code\Tycoon\TycoonDlg.cpp(107) : error C2228: left of '.Add' must have class/struct/union type
F:\Documents and Settings\Administrator\My Documents\Arun\Code\Tycoon\TycoonDlg.cpp(107) : error C2065: 'output' : undeclared identifier
This is the code from my file.
void CTycoonDlg::OnIncrease()
{
cash++;
//On Click, Display in ListBox "You currently have $(cash) with you."
CString str;
CString output;
str.Format("%i", cash);//make a string from your number
output = "You have \"" + str + "\"dollars in your account.";//make nice ans fluffy string. (\" is a " character in your string)
}
void CTycoonDlg::OnList()
{
listbox.Add(output);//add to listbox (could be AddString or something don't know by heart)
}
I know I said "x" would be the variable, but I decided it was too confusing and changed it to "cash".

Nothing actually, crazy developers like myself often set crazy comment to try and be funny.
ok, CString output is declared LOCAL in your case. Put it in your .h file or somewhere on top of your .cpp file. (but under the include part)
"listbox" is an unknown Object (or variable) in your case.
go to the resources, right click your list box and choose "add member variable". Name it and use this name instead of "listbox"
output = "You have \"" + str + "\"dollars in your account."
make it:
output = "You have " + str + " dollars in your account.";
then you don't have the " in your text.
try this and you'll get less errors.
btw: I explained it taken in account you have Visual Studio. If you don't, you have to create your listbox manually. =>( http://msdn.microsoft.com[^] search on CListBox)

hey all
i know that the code is
ShellExecute(NULL, "open", "http://",NULL, NULL,SW_SHOWNORMAL);
but if i want to hide the window of the IE... is there any way?
|
|
|
|

Hi,
ShellExecute(NULL, "iexplore", "about:blank",NULL, NULL,SW_SHOWNORMAL);
Width CreateProcess() function can obtain more information about new process:

Try SW_HIDE rather than SW_SHOWNORMAL.

if you want to hide or show it later you can do so using ShowWindow();
the problem is you will have to obtain a handle ot the window
example (hide)
ShowWindow( hWnd, SW_HIDE );
example (show)
ShowWindow( hWnd, SW_SHOW );
if im guessing correctly you want to get the user to go to a web-site, without them knowing it right?
if this is true i suggest just learning how to use sockets
Nishant (i think i spelled it right) has a very good artical on using sockets
|
|
|
|

you are right archer.. i want the user get the website without knowing it...i will try to find more info about socket.. and sure i will replay here for more info.
thanks : )

Instead of running IE, you could use UrlDownloadFile() to download a file or use my WebResourceProvider[^] class to write a crawler.
