that is 2 to 3 when lbl is 100 that means he knows the length of string without the string i got.
lbl10.exe no rebuild , lbl-100.exe no rebuild ...
thanks

Hi,
I am using the DhcpRequestParams() API to retrieve the server option IDs from the DHCP server. I get the correct option values for the first time. If I make any changes to the server option IDs, and then again call the same API, it retrieves the old option values and not the changed new value. Any idea how I could retrieve the new values?
Thanks in advance,
AJ

How are you calling it?

Hello
I have a problem on how to hide an application running in hidden mode. I found a code to hide the window. This code will hide all windows including the dos window. The code is :-
<br />
#include <windows.h><br />
<br />
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)<br />
{<br />
while(1)<br />
{<br />
Sleep(1000);<br />
}<br />
<br />
return 0;<br />
}<br />
<br />
main()<br />
{ <br />
<br />
}<br />
<br />
</windows.h>
Im not sure what does this code do but since i already test the code, it really hides the dos window.
A brief about my system, i created client server based application using a win32 console application where the client will communicate and send messages to the server. The network part has already be done and the client currently can send messages to the server meanwhile the server has no problem to display the sent messages from the client. So this means that the client-server part has no problem. One of the requirement of my application is that the client application must be hidden from the user. So, I used the code above to hide the dos window from being seen by the user. At first, the code above didnt work (the dos window can still be seen). There was no error but after i had done some research, i realize that it couldn't work because the linker setting of the project under system tab is by default set to Console (/SUBSYSTEM:CONSOLE). So i changed this setting to Windows (/SUBSYSTEM:WINDOWS). Then after i change these settings, the code above works (the dos window is hidden). How did i know that the code works is because i checked the Windows Task Manager and i saw that under processes tab, there is my *.exe is executing. The problem is that the network part didnt work since the server didnt receive any messages from the client.
Then i differentiate the application running under Windows (/SUBSYSTEM:WINDOWS) with the one running under Console (/SUBSYSTEM:CONSOLE). I realize that when the application is running under /subsystem:windows and it is hidden, the windows task manager will display only at the processes running. For instance: my project name is hidden.exe. So, hidden.exe will be displayed only at the Processes running tab. There is no display under the Application running tab. But when i change to /subsystem:console and the dos window can be seen by user, i found that the windows task manager will display hidden.exe at the Application tab meanwhile at the Processes tab, it only display cmd.exe is running, not hidden.exe.
Im not sure is this the correct method to hide a window from users view. My priority is that the client application running under dos window cannot be seen by the user which means it is hidden and at the same time, the client which is hidden is sending messages to the server and the user doesnt know that the client application is sending messages to the server. Is there any opinion or help? I really appreciate for any help or opinion. Thanks

if /SUBSYSTEM is console, that is console application, by default system provides a console, i am not sure whether it can be disabled, In linux, for console applications, console is not visible until an console IO statement is executed.
In your sample, main() is not going to execute in (/SUBSYSTEM:WINDOWS) and WinMain is not going to execute in (/SUBSYSTEM:CONSOLE).
However since in (/SUBSYSTEM:WINDOWS) application, since u r not creating any windows, it seems the application is hidden.
1)If you want any user interface and want to hide whenever possible, go for windows application and use ShowWindow() API to hide.
If you never want to have an user interface in this application,
2) still u can use windows application with no window created or
3) go for "Windows Service Application", Windows Service application is usually meant for background and long run task.

Ok. understand now. So, since i dont want any windows interface for this application, I would like to choose either option 2 or 3. (Use windows application with no window created or go for windows service application"
Let say if i choose option 2. How can i create windows application without affecting my network application (client/server) which has been coded in C. Must i use MFC or there are other options which is much more easier to use to create windows application and it can also integrate my client/server application in C.
If i choose option 3, does windows service application accepts C as the programming platform? Can it be coded in Microsoft Visual Studio or it uses another programming application. Another thing, must i change the whole code of my client/server or i can use the previous one, just change the platform from visual studio to windows service application. Actually im kinda new to programming so im weak in choosing the requirements.
Lastly, thank you from your previous reply and it really helps. Thanks again

First of all, it seems you need to be familiar with basics of windows programming, that can answer almost everything yourself in this context.

since u don't need UI, u can avoid MFC for now. Infact u can integrate your C Code with both MFC and WIN32.
Kogee San wrote: If i choose option 3, ...
WIN32, Win Service application can be implemented in VC, VC is C + Microsoft specifics
there should be more than these 3 option to do this, it depends on the level of expertise in windows programming i can rate myself (1/10)

If the code snippet is troubling you, it's obvious you need to start with the very basics, and leave window hiding for another time.

Hi,
I have a program where I need to check whether 10s has elapsed before setting something to failed.
I have used clock().
Unfortunately, if the real time updates (for whatever reason e.g. I manually change the clock from 10:30 to 11:30), clock() updates too thereby causing my code to flag an error as it thinks more than 10s has elapsed.
Does anyone know of a way that I can check the elapsed time so that any changes to the real time don't affect it?
I hope that made sense!
Thanks in advance.

Hi ,
I have a CStringList that contains some filepaths, these paths need to be passed into a function:
eg: GetNewXML(LPTSTR PreviewFileArray[],int count)
How can I construct a LPTSTR array from CStringList?
thanks
|

Are you sure that you really need LPTSTR (don't you need LPCTSTR)?
As stated, you probably have to copy all the strings.

sorry, what do you mean "copy all the strings. "?
can you provide me a code? thanks
|

|

Yes the function prototype implies such copy.

however, I can't initialize the array like this:
LPTSTR[] files = new LPTSTR[count];
do you mean copy character by:
LPTSTR a = list.GetAt(0).CopyChars?

change to

Or another suggestion (if you can change the function signature): just pass the string array as a constant reference instead.
void GetNewXML(const CStringList& myList);
You wrote the GetNewXML function ?
|
|
|
|
|
sorry that I can't change the interface for function "GetNewXML", coz it has been written by pervious staff.
so I trying to do, but not work
/*
LPTSTR[] files = new LPTSTR[count];
for(int i=0; i< count ; i++)
{
files[i] = bmpList.GetAt(i).GetBuffer();
}
*/
|
|

Well, in principle, you can do the really weird thing you suggested:
LPTSTR* files = new LPTSTR[count];
for(int i=0; i< count ; i++)
{
files[i] = bmpList.GetAt(i).GetBuffer();
}
GetNewXML(files, count);
for(int i=0; i< count ; i++)
{
files[i] = bmpList.GetAt(i).ReleaseBuffer();
}
delete [] files;

I think you didn't really understand what the function accept: the function doesn't accept an array of strings, but one single string (and the count argument is the size of this string). So, you need to pass each string separately. Basically, what you'll need to do is loop through your string array, create a LPTSTR array of the size of the string and pass it to your function, then delete it.
That's completely stupid because if your previous team would have been smart enough so that they passed the string as a constant (LPCTSTR instead of a LPTSTR), then you wouldn't have to create a new string buffer, copy the string in it, pass it to the function and delete it. You would just have to pass the CString object (and it would have been automatically converted).
Oops, I forgot the [] after the first argument  . So, forget what I said...
