Do you have the following line?

#include <setupapi.h>

Yes.

I #included the following:
#include "windows.h"
#include "stdlib.h"
#include "objbase.h"
#include "setupapi.h"
#include "winioctl.h"
#include "process.h"
#include "memory.h"
#include "stdafx.h"

Since the SetupAPI.h file defines the SP_DEVICE_INTERFACE_DATA structure in this manner:

#if _SETUPAPI_VER >= 0x0501
    . . .
    typedef ..... SP_DEVICE_INTERFACE_DATA;
    . . .
#endif

I think you have to add a definition like

#define _SETUPAPI_VER 0x0501

before all of your #include.

how do you know to do that?

I used Search operation within *.h files supplied with Visual Studio, for "SP_DEVICE_INTERFACE_DATA" string. Thus I found the SetupAPI.h file and then I analyzed it.

nope... still didn't work.
I've also made sure that the setupapi.lib is also part of the options for the linker and that I've provided a path to the lib files in the project properties.

how to send unicode text in XlTable

16-Jun-06 5:56

Today it was reported a similar problem with other header files.

The solution was to put your #include after "stdafx.h":

#include "stdafx.h"
#include <windows.h>
#include <stdlib.h>
#include <objbase.h>
#include <setupapi.h>
#include <winioctl.h>
#include <process.h>
#include <memory.h>

If it works, you can move your #include to the end of "stdafx.h" file and then rebuild the solution. In this case, next time your file will be compiled faster.

Hi XlTable Structure has 255 as the max length for a string block
so if I want to send a unicode text I'm restricted with 127 max
and the worst is that when an application like Excel expect to have
- lets say 200 - chars each block then we can't send unicode text
so any Idea how can I send unicode using XlTable
-if any one knows other format except tdtString that do the job -

As you can also see I have dynamically allocated them as well. The reason for doing this is because I dont want to make sure that the dialog boxes dont hog a lot of memory. The problem I am receiving is that once this dialog box is called that contains the multiple tabs, I get an error once I close, reopen and close once again this specific dialog box. The error is as follows:

Debug Assertion Failed!

Program: C:/.../RS_Stats32.exe
File: dbgdel.cpp
Line: 47

Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

I looked on MSDN but it doesnt offer any helpful advice on how I fix this error. I know its an issue with dynamically allocating those variables because I did not receive this error when the variables were just static and not dynamically allocated. My questions basically are:

1) Is it possible to dynamically allocate static variables, and allow the variables to dynamically allocated and destroyed once a routine has been completed? If so how?

2) Is making the hwnd variables dynamically allocated worth it? Does it actually save a considerable amount of memory?

Any help would be appreciated Smile | :)

Thanks,

Robbie

Instead of this try to call the EndDialog(hwnd, 0); after deleting all the tabs.it may resolve your problem Unsure | :~

Hey man,

lol thanks for the fix, but I ran into a BIG problem. When I ran the program and closed the dialog box, I got my 8th (i think?) ever BSoD and some very weird exorcist sounds coming from my speakers. So dont think that worked out too well. Any other ides you may have?

I think the problem is because of multiple delete operations performed on the same pointer. You probably believe that a line like

static HWND* tab1_hwnd = new HWND;

within a function allocates the object on each execution of that function. This is not true: the pointer is allocated once.

You can change it like this:

static HWND* tab1_hwnd = NULL;
...
case WM_INITDIALOG:
    tab1_hwnd = new HWND;
    . . .

case WM_CLOSE:
    ::DestroyWindow(*tab1_hwnd);
    delete tab1_hwnd;
    tab1_hwnd = NULL;
    . . .

Actually HWND is not so a big object. It takes only 4 bytes. Therefore you can work without pointers:

static HWND tab1_hwnd = NULL;

Ok thats cool, I'll just take out the pointers since its easier that way. Thanks for your help guys.

Hi All
I have been puzzelled in a problem,
What have to do is, that I have some file names ( like 000001.doc, programming.doc, etc.) now I have to find out the files that are in hexadecimal (leaving file extension).

Please guide me to find out this

Thanks

Use isxdigit() on the file's name.

Ahh david's is a much easier way. Its in the following library as well!

#include <ctype.h>
int isxdigit(int c);

capricious_00116-Jun-06 4:06

16-Jun-06 4:06

1) Retrieve the file list

2) Loop through each file. For every File name, loop through its name until the extension is reached and check to see if each character is either [0-9] or [A-F]. If its not, just do continue; and start back at the beginning of the loop again. Use this website to utilize the ANSI character set.

http://www.alanwood.net/demos/ansi.html

Remember, the letters can be either lower case or uppercase and have different ANSI codes.

3) Record the file names in an array. (Create a dynamic allocated array for big file names).

CString's Format Fuction confusion

16-Jun-06 4:11

Try this idea:

char name[100] = "......." ; // the file's name without extension
char * p;
strtoul(name, &p, 16);

if( *p == 0)
{
    // the name is like a hexadecimal number, or is empty
}
else
{
    // the name is not like a hexadecimal number
}

Hope it helps.

Re: CString's Format Fuction confusion

I'm trying to in corporate a \n in a CString variable I thought that you could use the format function to do that. Here's the code:

CString look;
look.Format("Original text: <%s>\n"
"Uppered: <%s>\n"
"CompareNoCase says they differ!\n"
"Lowered again: <%s>\n\n"
"Conclusion: CompareNoCase doesn't work correctly!");
AfxMessageBox(look);

But then I keep getting the following errors:
c:\documents and settings\....cpp(102) : error C2664: 'void ATL::CStringT<basetype,stringtraits>::Format(const wchar_t *,...)' : cannot convert parameter 1 from 'const char [137]' to 'const wchar_t *'
with

BaseType=wchar_t,
StringTraits=StrTraitMFC_DLL<wchar_t>
]
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Build log was saved at "file://c:\Documents and Settings\kmil\Desktop\tst\LEDs_try2\LEDs_try2\Debug\BuildLog.htm"

could someone explain to me what i'm doing wrong?

Thanks,

if you use a parameter in the format of the CString::Format() function, you must provide an additionnal parameter...

CString str;
str.Format("Hello %s...!", "Kitty");

Instead of:

"Uppered: <%s>\n"
"CompareNoCase says they differ!\n"
"Lowered again: <%s>\n\n"
"Conclusion: CompareNoCase doesn't work correctly!"

try this:

_T("Original text: <%s>\n")
_T("Uppered: <%s>\n")
_T("CompareNoCase says they differ!\n")
_T("Lowered again: <%s>\n\n")
_T("Conclusion: CompareNoCase doesn't work correctly!")

This is because you are compiling an Unicode application. The _T macro allows you to make programs for both Unicode and ANSI modes.
