Hi,
I'm using Visual Studio 2005 C++/CLI. I have an application that I would like to create a new version of. Obviously I don't want to recreate a bunch of dialog boxes, etc., so I copied my application from c:/Visual Studio 2005 Applications/myAppVersion1/myApp to c:/Visual Studio 2005 Applications/myAppVersion2/myApp. Here is my problem... I click on c:/Visual Studio 2005 Applications/myAppVersion2/myApp.sln to bring up Visual Studio 2005. Then I clean and rebuild the solution but when I run myApp there is a line that gets the current directory System::IO::Directory::GetCurrentDirectory() and it uses the directory for myAppVersion1. If I am running the solution from myAppVersion2 directory then why does GetCurrentDirectory() return the myAppVersion1 directory?
Thanks,
Buck

In the project's debugger settings, do you have a working directory specified?
In general, your app should set the working directory and not assume a certain
location

I encountered an absolutely insane problem with BinaryStream I/O of native classes that I was wondering if someone could shed some light on. I do have a work-around, but the whole thing just doesn't make any sense to me...
First, I have a class, "CMyBinaryIO" to handle the streaming. The Save(IntPtr myData, int iSize) method takes 2 params: an IntPtr to the data, and a integer to indicate the expected byte size. I use Marshal::Copy(...) to copy the structue into an array of bytes, and then pass that array to the BinaryStream::Write(...) method. Simple enough.
OK. Now the dirt... Consider the following, simple code snippets:
<br />
UMyParent<br />
{<br />
public:<br />
int iParentA, iParentB;<br />
};<br />
<br />
UMyHelper<br />
{<br />
public:<br />
int iHelpA, iHelpB;<br />
};<br />
<br />
UMyChild : public UMyParent<br />
{<br />
public:<br />
int iChildA, iChildB;<br />
UMyHelper uChildHelp;<br />
};<br />
If UMyChild has a Save() method that does this...
<br />
CMyBinaryIO::Save((IntPtr)this, sizeof(UMyChild));<br />
...it works. I can do a similar read operation and retrieve all the data properly. HOWEVER, I cannot read/write the binary file in any environment other than the one it was created in. In other words, if I was running the application through the IDE, I cannot read the file by running the EXE directly!!! If I create a file by running the app directly, I can't even read the file by running the exe directly on a different computer!!!
To be specific, if I created the file running through the IDE and I try to read the file by direct execution, the program acts like it read the data just fine. However, when I try to invoke any other method in the UMyChild class (maybe pChildInstance->DoSomething()), I instantly get a crash with a nice message that says something about not being able to access memory, and that the memory is possibly corrupt.
Now, here's the real confusing part. If I do this in the UMyChild::Save() method...
<br />
CMyBinaryIO::Save((IntPtr)&iParentA, sizeof(int));<br />
CMyBinaryIO::Save((IntPtr)&iParentB, sizeof(int));<br />
CMyBinaryIO::Save((IntPtr)&iChildA, sizeof(int));<br />
CMyBinaryIO::Save((IntPtr)&iChildB, sizeof(int));<br />
CMyBinaryIO::Save((IntPtr)&uChildHelp, sizeof(UMyHelper));<br />
...the the file can be created and re-read on ANY machine, and is completely cross-compatible between IDE and "live" execution. And when I call pChildInstance->DoSomething(), I don't get the corrupted memory messages!!!
I thought it might have something to do with .NET trying to write complex unmanaged types. But look closely at the code... The app does not require the UMyHelper members to be written one field at a time. The "uChildHelp" member can still be written as one chunk of data.
Does anyone have any ideas on how this could possibly be? Thank God I can at least do the single-member read/write to get around the issue, but it doesn't seem like I should have to. Why can't I pass the "this" member with the appropriate size calculation of the inherited class with all its members?
Thanks.

First, the code you posted does not even compile. Second you are doing what when reading? You did not post any reading code.

What method, there is no method in that class.

I was providing abbreviated code, as the focus of the problem is on the data members, not the methods. In "real life", the code is thousands of lines long, containing scores of members and hundreds of methods. The "DoSomething()" method I refer to is actually a method containing several hundred lines of OpenGL rendering code. This code is all straight-forward calls to the OpenGL API, using the class members to define 3D coordinates, rotations, transformations, etc. There are no tricky pointer operations or anything like that which could possibly be triggering the so-called memory errors.
Remember, all of my code works fine if either (1.) I only open the saved binary file while running the application in the same mode that created the file (IDE vs. "live" execution) OR (2.) I use the above-described work-around. Since I can get consistent behavior in either circumstance, I am convinced the problem lies in the BinaryStream class when trying to serialize unmanaged classes as one solid memory chunk.

Hi,
i developed a C++/CLR App using Visual Studio 2008. The following are the settings
1. Developed using VS2008, Featurepack was installed but not used(april) (x86 machine Vista SP1)
2. /clr:pure, pure .NET, no native code.
3. Target framework set to 2.0
4. I used cliext STL/CLR in the project.
5. Release mode
When i try to distribute the compiled exe on a Windows Xp SP2 PC, i tried the following and the program would not run.
1. I copied the exe to target machine
2. Installed .NET framework 2.0
3. Ran the app, and an error occurs - "The application failed to start because of configuration incorrect..."
I then tried to install
4. Install VCredist 2008
5. Ran the app, the app launches but a new error occurs
"System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualC.STLCLR, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.VisualC.STLCLR, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ...."
I then installed .NET framework 3.5 and the app finally runs perfectly.
What i dont understand is,
1. Why do i need the VS2008 redist? I thought this was only for native code. I didnt use any native code in my assembly, in fact i compiled as /clr:pure!
Checking the .exe using dependecywalker shows that the exe only depends on MSCOREE.DLL, no MFC,CRT etc.
2. Why did the compilation proceeded even in VS2008 when i selected the target framework to be 2.0. I used STL/CLR in my app, why didnt the compiler tell me that STL/CLR is part of .NET 3.5 and produce an error during compilation?
3. I was expecting it to run properly with .NET framework 2.0 installed only, just like any other C# code targetted for this framework. I didnt expect vcredist and .net 3.5 required..
Can anyone clarify this? Anyone had this problem, or my approach was incorrect?
Thanks

Might it be the manifest file that is your issue ?

I have linked a C++ static library to a Windows Forms Application. The static library contains a singleton:
namespace Lorenzo
{ class VendingMachine
{ ...
I am trying to invoke a function in the singleton from inside a button’s click event with the following code:
VendingMachine::Instance()-> function();
I get the following linker errors.
error LNK2028: unresolved token (0A00000D) "public: static class Lorenzo::VendingMachine * __clrcall Lorenzo::VendingMachine::Instance(void)" (?Instance@VendingMachine@ Lorenzo@@$$FSMPAV12@XZ) referenced in function "private: void __clrcall VendingMachineControls::Form1::chcolateSelectnButon_Click(class System::Object ^,class System::EventArgs ^)" (?chcolateSelectnButon_Click@Form1@VendingMachineControls@@$$FA$AAMXP$AAVObject@System@@P$AAVEventArgs@4@@Z) Vending Machine Controls.obj
error LNK2019: unresolved external symbol "public: int __clrcall Lorenzo::VendingMachine::makeSelection(int)const " (?makeSelection@VendingMachine@ Lorenzo@@$$FQBMHH@Z) referenced in function "private: void __clrcall VendingMachineControls::Form1::chcolateSelectnButon_Click(class System::Object ^,class System::EventArgs ^)" (?chcolateSelectnButon_Click@Form1@VendingMachineControls@@$$FA$AAMXP$AAVObject@System@@P$AAVEventArgs@4@@Z) Vending Machine Controls.obj
The library works with a console application, so there is no problem with the library. I would be grateful if someone could tell me what the linker errors mean or at least give me a hint as to what might have caused them. I would be very grateful for all help.

Question, you are using C++ and the .NET platform to write software for a vending machine but you don't know what a link error is, is that correct? If so, why would you choose to use a language for your project that you don't know how to use? I find this confusing at best.

Hi, I am using Visual Studio 2005 C++/CLI and I need to create an installer for an application. The documentation I have says to create a new project and select "InstallShield 12 Projects" but there is no selection available. Does anyone have information on how to get an installer created for a completed application?
Thanks,
Buck
