using namespace but still have to qualify command

Hi, I am new to CLI. Using Visual Studio 2005 C++/CLI. I have a simple app that I am beginning to develop. I created a CLR Windows Form app and gave the form1.h design some menu options. Then double clicked on a menu item and went to the generated function to add an OpenFileDialog. Just above the definition of the Form1 class I have using namespace defined for System, System::IO, System::Windows::Forms, and some other namespaces that I don't believe apply here. If I qualify the dialog result as System::Windows::Forms::DialogResult::OK then after the last double colon the intellisense puts up a list of results (OK, ABORT, etc.). But if I just type DialogResult:: then intellisense simply lets me choose between get() and set() properties so if I type if(openFileDialog->ShowFileDialog() == DialogResult::get()) I guess my question is...if the namespace that includes DialogResult is included why doesn't DialogResult:: give me a list of the possible results? Another issue is that I have another machine that uses the notation of ::DialogResult but if I try this on this machine I get a "not part of the global namespace" error. Any insight would be appreciated.

I left out half a sentence. ...so If I type "if(openFileDialog->ShowDialog() == DialogResult::get()) the conditional fails even though I clicked the OK button. I guess my question is...

Hello aefmaaradji,

Use String::Format (String is in namespace System) instead of string.Format.

So after much jubulation and sacrifices to the gods of managed/native code I continued on with my Outlook Addin.

The native code I have is working fine untill I introduce a thread to take the workload away from the GUI thread. Now the exact same code is throwing:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Once I have created the thread I grab a list of the items I'm interested in from Outlook (which is the main thread). I then take each of these managed object and retrive the native object (still reprisented as a System.Object) and pass them over to my C++/Cli. In the managed C++/Cli I use System::Runtime::InteropServices::Marshal::GetIUnknownForObject(iMessage); to retrive and IntPtr and then LPMESSAGE iMessageToSave = (LPMESSAGE)(ipMsg.ToPointer()); to convert it into a native object. The native object is passed to the native C++ method which dies as soon as I try to pIMessageToSave->CopyTo(), where pIMessageToSave is the same native object.

As I said ... it works fine without threading but dies with it :S

Any suggestions?

game map loading

I gots some maps im trying to load for a game i'm trying to make.

these maps are in a folder called Data

I have a message box that comes up asking which of the two maps i have made i want to load.
I have made done char mapToLoad[200]; at the top.

<br />
if (MessageBox(NULL,"Load world 1?","Load World",MB_YESNO|MB_ICONQUESTION)==IDYES)<br />
{<br />
    mapToLoad = "Data/World1.txt";        <br />
}<br />
else <br />
{ <br />
    mapToLoad = "Data/World.txt";<br />
}<br />

Do i have to do mapToLoad[1] = D
mapToLoad[2] = A and so on? i was hoping there was an easier way thats why i tried this.

After that i have
filein = fopen(mapToLoad, "rt");
This should work right?

The majority of code i have in the project is from the NeHe opengl tutorial here http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=10[^]

thx

Use a list view or a combo box to allow the user to choose the map he wants

I probly should have said this earlier. I am using bloodshed dev-cpp not microsoft visual studio. So i

don't have access to those sorts of things. And i think i mentioned before i'm using opengl. I dont

think a windows combo box will work with an opengl program?
The only other way i can think of doing it is to have a seperate loading thing for each map and go if

<br />
messagebox == true <br />
{<br />
     whole loading procedure for world.txt<br />
}<br />
else<br />
{<br />
     whole loading procedure for world1.txt<br />
}<br />

this seems like alot of extra code to be compiling to me.
So i don't think this is a viable option either.

I really just need to know how to stick the location of the file into a char and then use that char in

place of the first char argument of fopen(const char*, const char*)

thx

Probably, you also don't have access to .NET, and you're therefore asking in the wrong forum.

Thats annoying coz i really don't want to use the microsoft visual studio i have installed. Because then i would probably have to use .net and if i want to port to other platforms it would make it difficult.

run an EXE for all users on a computer

have an application in visual c++ relating to client and server. this appliaction does many types of work like getting all user names logged on to computers,remote shutdown,remote logoff, getting the remote desktop view and many others types of functioning related to "lan monitoring" through server. but for this , client application has to be executed all the time whenever any user logon through his local account.
but the problem is that I couldn't find any way to execute the "client exe" automatically whenever any user logon through his/her local account.But I could execute the client exe automatically for the administrator by making changes in the registry but I have to execute it "for all users".

So please help me to find any way to execute the client exe for all users automatically whenever they logon through their local account.Is there any win api or by making any registry changes or any program which can call the exe automatically whenever any user login.

ps:since this is all a part of a domain so all the other users are less priviliged than admin

Ok so I'll start by declaring my undying love for C# :P it's my primary language and I try to stick to the managed world where ever possible. This time though I need to use some stuff where pInvoke just wont cut it so I'm using my lacking and very dodgy C++/Cli skills :P so please forgive me if I say anything stupid Wink | ;)

I'm currently working with this MAPI function:
OpenIMsgOnIStg[^]

Due to the wonderful fact that it requires Memory Management Functions to be passed to it:

lpAllocateBuffer
[in] Pointer to the MAPIAllocateBuffer function, to be used where required by MAPI to allocate memory.

lpAllocateMore
[in] Pointer to the MAPIAllocateMore function, to be used where required by MAPI to allocate additional memory.

lpFreeBuffer
[in] Pointer to the MAPIFreeBuffer function, to be used where required by MAPI to free memory.

I'm not even going to go near it with pInvoke.

I've translated this article:
INFO: Save Message to MSG Compound File[^]
into a standalone native method and I'm now trying to put together the C++/Cli code to act as the go between.

The biggest problem I'm currently facing is trying to convert a System::Object into a LPMESSAGE. None of the casts seem to want to work and I'm not sure of the next direction to try :S does anyone have any suggestions on how to cast/convert?

Well I'm not sure if this is the cleanest way of doing it but it works Big Grin | :-D

System::IntPtr ipMsg = System::Runtime::InteropServices::Marshal::GetIUnknownForObject(iMessage);
LPMESSAGE iMessageToSave = (LPMESSAGE)(ipMsg.ToPointer());

Obviously it was the right underlying native type otherwise the way I use it later would have bombed. I'm quite chuffed with how relativly easy and painless this was Smile | :)

need a similar function as "getchar()"

10-Jul-07 22:00

if I am using getchar(), then the execution of the program will stop here if no input is given.

could someone help me figure out if there is another way? Aim: while any input is given, save it to a variable, if not, keep on executing program without stop.

I have used multithread, but it did not work well when I put it running at background.

I am using C

Then you can't be using .NET and you're in the wrong forum. Try the visual C++ forum.
