You can use only integral expressions as the switch expression.
What type of array is it?
If it is a character array, you must use the string functions in the if statement.
If it is an integral array, you are storing multiple values. You must use the array subscript [] to specify which element to check.

I tried using [].
Will I have to use it for each element of the array?
|
|
|
|

Yes.
Say you have an array:
int p[] = { 5, 4, 3, 2, 1 };
then to get the 3rd element use:
int x = p[2];
This will set x to 3. Remember, arrays start at index 0 instead of 1.
To loop through
for( int 1 = 0; i < 5; i++ ) {
x = p[i];
}

Yes. You will have 16 array elements ranging from swt[0] to swt[15]

Hi,
my VC++ 6.0 application calls my check_user_sp stored procedure that calls the sys.sp_helpuser system stored procedure:
-----
CREATE PROCEDURE check_user_sp
@inp_user VARCHAR(20)
AS
EXEC sp_helpuser @inp_user
-----
I have no problem running the application against database on the 2000 sql server(2000 - 8.00.760), but I get 'Invalid character value for cast specification' error with the same database on the 2005 sql server(2005 - 9.00.1399.06).
the sp_helpuser is dated 1996/08/14 10:33 on both 2000 and 2005 server, and I don't get error when exec my get_user_sp in the 2005 sql server management studio.
what is 2005 sql server doing to cause this?
THANKING FOR YOUR HELP!

Hello!
try checking database collation settings / server collation settings.
|
|
|
|
|
thanks! I checked and they have the same collation seetings.
I looked into the sp_helpuser code and then realized that the one in sql server 2005 returns 7 columns but the one in sql server 2000 returns 6. My application expects 6 columns and gets the error with sql server 2005.

Hi,
I am sort of familiar with the functions:
GetPrivateProfileString()
WritePrivateProfileString()
used with parsing a .INI file.
What I want to do is get/set the Section names within a .INI file.
For example, if I had the .INI file
[c:\root\database\images\country.dat]
value1=1
value2=1024
value3=500
[FILENAMES]
0=c:\imagery\color\map1.jpg
1=c:\imagery\topology\elevation.dat
[c:\imagery\color\map1.jpg]
MapValue1=1
MapValue2=255:255:255
[c:\imagery\topology\elevation.dat]
TopologyData1=0
TopologyData2=1000
How can I dynamically access the Section names, within the brackets [ ], when I don't know what they could contain? AND can I change these (like re-path) and then update the .INI file?
Thank you.

|

That looks to be exactly what I need, half of it anyways. The other half is modifying/writing back these section names.
Thanks a million!

Use GetPrivateProfileString(NULL, ...).

Sorry, but this is the closest match forum I could find on CP:
I have a native C dll that exports one function besides DllEntryPoint, FuncX. I'm trying to find out how FuncX communicates with it's caller, because it has a void return type and no parameters. When I call it from a C# harness, I get an AccessViolationException - Attempted to read or write protected memory.
I have a hunch that its client application may allocate a buffer for sending or receiving values from the dll. Is this a valid hunch?
I can't debug the client application because for some reason it doesn't run, so I can't start it and attach to the process. I can, however, disassemble it in IDA Pro, but don't know how to, if I can, try and debug it in there.

Can you debug it from a C or C++ client, so you can step into the function in (native) disassembly mode?

So there's no visible interface? That says global data to me - which requires a commonly defined symbol.

Sounds possible - but how does the buffer get into FuncX?

I'd have to write that client, after a ten minute C refresher, but it's possible, and I'm not scared.Stuart Dootson wrote: Sounds possible - but how does the buffer get into FuncX?
I suspect it's at something like a constant, known offset or address in the calling code, if that's at all possible.
Right now I'm busy with an IDA Pro tutorial, to get started exploring the internals with some muscle and some baby help behind me.

That sounds scary  Especially as DLLs can be relocated...
Brady Kelly wrote: I'd have to write that client, after a ten minute C refresher, but it's possible, and I'm not scared.
extern __declspec(dllexport) void FuncX();
#pragma comment(lib, "whatever-the-DLLs-lib-file-is");
int main(int argc, char** argv)
{
FuncX();
}
or if you don't have a lib file:
#include <Windows.h>
typedef void (*FuncXType)();
int main(int argc, char** argv)
{
HMODULE myDll = ::LoadLibrary(DLL-name);
FuncXType pFuncX = (FuncXType)GetProcAddress(myDll, "FuncX");
pFuncX();
}

How to parse a CString: 1,1,E1,0.13060,-0.40193,-0.90631
which is a line delimited with commas of a mixture of numvers and characters.
I can read in: 1,1,E1,0.13060,-0.40193,-0.90631
using:
fscanf( f_ptr1,"%s\n",headline.GetBuffer(MAX_PATH));
headline.ReleaseBuffer();
Thanks

Something like:
CString headline;
...
CString Token;
int Pos = 0;
while (!(Token = headline.Tokenize(_T(","), Pos)).IsEmpty())
{
}

After trying yours, I got:
'Tokenize' : is not a member of 'CString'
Please check and help
|
|
|
|

Works for me, maybe it is some version difference or so...hmmm...that CString is the MFC CString, not some custom class, right?

Yes, CString is a MFC CString. I am using C++ 6.
|
|
|
|

7 here, i guess Tokenize didn't exist in version 6 yet. Well, you can either try using this[^], or hope someone who knows version 6 comes along and helps you.

Thanks. I think I need to port my program to a newer version.
Is it be much trouble to use a newer version of compiler for the present program ?
Any comments
Thanks.

By using AfxExtractSubString().
Also, since you are using MFC, you can forgo the use of FILE and fscanf() and use CStdioFile instead. Calling GetBuffer() like you are is unnecessary and potentially dangerous.
