No, there is no such thing as a "micro .NET" doing everything the framework does but at 1/10th the size 
There's no way around installing the framework on a client machine at least once. Newer windows versions already have .NET preinstalled, so in the future this will not be such a big point.
If you're only targetting people who have to download everything over a 56k modem then perhaps you should really opt for a different platform. Or make an ASP.NET application, so that you can use the advantages of .NET on the server side and your clients only need a browser.

Hi everybody,
I have a simple question but no answers to this...
On a C# client, I have 2 threads running: one for GUI and another one created for webservice synchronous calls.
When I click a button, I call 'SoapHttpClientProtocol.Abort()' on the GUI thread.
It then should abort a lengthy call (blocked) on a the worker thread and release the latter.
But it doesn't...
WHat's wrong!??!? 
Thanks in advance!

Hi,
A client just sent me an obscure exception stacktrace that he got.
My guess is that it's a "one shot" exception (won't happen again) but still, I'd like to know what's going on. It doesn't even seem to have to do with my code.
How can I prevent such exceptions (I receive obscure exceptions like that once in a while)
Thanks!
Carl

Hi
i would like to explain a situation where this type of error might occur. In a windows form having a toolbar icon, place the cursor on any of the icons in the toolbar and try to do any other operation using the keyboard (may be by pressing the hot key combination). In these type of scenarios such error occurs... because when you have placed the cursor on the icon tooltip is being displayed and when u try to invoke any other procedure u get this error.

Any way to prevent this exception?

Hi,
Open the Setup Project and then follow the below given steps:
Installing an Assembly to the Global Assembly Cache upon Installation
You can use the File System Editor to install an assembly to the Global Assembly Cache upon installation. To do so, the assembly must be incorporated in the setup project as a loose file and not compressed with the other project output. To install the assembly to the Global Assembly Cache, you must first sign your assembly with a strong name. Once your assembly has been strongly named, all you need to do is add a Global Assembly Cache folder to the File System Editor and add your assembly to that folder. Upon installation, your assembly will be added to the Global Assembly Cache.
To install an assembly to the Global Assembly Cache on installation
Sign your assembly with a strong name.
After creating your setup project, open the File System Editor.
Right-click the left pane and choose Add Special Folder. In the shortcut menu, choose the Global Assembly Cache Folder.
In the left pane, right-click the Global Assembly Cache Folder. Choose Add, and then choose Assembly from the shortcut menu. Choose the appropriate assembly or browse to its location and click OK to add the assembly.
The assembly will be added to the Global Assembly Cache upon installation. If the assembly was not already a part of your setup project, it is added to it.
Regards,
Sukesh.

I have a C# winforms app which starts other processes using System.Diagnostics.Process.Start. This all works except when the process has actually started the winforms app puts itself in front of the process which has just started. Is there a way to suppress this behaviour?
Thanks in advance...

I'm having trouble understanding your question. Specially this part:

Could you clarify?

If the winforms app opens for example a Word document the sequence is as follows:
1) It opens the Word application.
2) The document is loaded in Word.
3) The winforms app main window put's itself in front of the Word main window.
In other words it seems that the winforms app does some sort of "SetForegroundWindow()" after the System.Diagnostics.Process.Start() returns.
Thanks,
Jan

A call to BringToFront() or Focus() after calling Process.Start should do the trick.
|
|
|
|

Further investigation has shown to me that the problem does not happen always. If I use Process.Start() to open a word or Excel document it does happen but if I open a text file it does not. When the problem occures the following happens:
1) Call Process.Start("somefile.doc");
2) The form receives a Form_Activated() event.
I should tell that the documents are opened via clicking in a treeview in which these files are listed.
I have found "sort of" a solution to the problem which pertains to calling SetForegroundWindow() on the MainWindowHandle of the created process when possible/necessary. Resulting in something like shown below. Sucks big time but it does the trick for now...
[DllImport("user32")]
private static extern IntPtr SetForegroundWindow( IntPtr hWnd );
[DllImport("user32")]
private static extern int GetAsyncKeyState( long vKey );
private void MainForm_Activated(object sender, System.EventArgs e)
{
try
{
if (( GetAsyncKeyState( 0x01 ) & ( 1 << 15 )) == ( 1 << 15 ) ||
( GetAsyncKeyState( 0x02 ) & ( 1 << 15 )) == ( 1 << 15 ) ||
( GetAsyncKeyState( 0x04 ) & ( 1 << 15 )) == ( 1 << 15 ))
{
prProc = null;
}
else if ( prProc != null )
{
if ( prProc.HasExited == false )
SetForegroundWindow( prProc.MainWindowHandle );
prProc = null;
}
}
catch ( InvalidOperationException )
{
}
}
Thanks...

Hi, i'm creating a C# DLL that i access from C++. The C# only connects to the database, creates three arrays, fills them, and passes the filled arrays (int[], double[], string[]) back to C++. The interop appears to be working fine, only my problem is in trying to convert a SAFEARRAY into an int[], double[] and string[] without compromising data integrity. This is my code to do this (at least for just the int[]):
C++:
SAFEARRAY * vi;
SAFEARRAYBOUND rgsaBound[1];
rgsaBound[0].lLbound = 0;
rgsaBound[0].cElements = 100;
vi = SafeArrayCreate(VT_INT, 1, rgsaBound);
spConnNET->Read();//this calls the method in C# to fill the arrays
//the code "spConnNET->ArrayInt()" retrieves the arrays from C#
HRESULT r = SafeArrayAccessData(vi, reinterpret_cast<void**>(spConnNET->ArrayInt()));
It is not changing it from a SAFEARRAY to an integer array though...can anyone tell me what i'm doing wrong, or what needs to be added?
thanks

just to update: i just changed my code to the following:
C++: (To convert safearray to int[])
//create SAFEARRAY to hold Integers:
SAFEARRAY * holdInt;
//safearray bounds:
SAFEARRAYBOUND bound[1];
bound[0].cElements = 100;
bound[0].lLbound = 0;
holdInt = SafeArrayCreate(VT_I4, 1, bound);
HRESULT r = SafeArrayCopyData(spConnNET->ArrayInt(), holdInt);
LONG pos[1];
LONG hold;
for(int h = 0; h < 100; h++)
{
pos[0] = h;
if (SafeArrayGetElement(holdInt, pos, (void *)&hold) == S_OK)
{
cout << hold << endl;
}
else
{
cout << "something's wrong" << endl;
}
}
Now, it prints out a series of "0's" and i know that's not what the result should be.

HI all,
I am facing a problem in accessing a VC++ 6.0 ATL COM object via a .Net application
The atl com dll is accessing another dll called OTAClient80.dll
The following piece of code has been written in ATL COM:
/* START OF CODE SNIPPET */
STDMETHODIMP TDDOORSApi::temp(int *count)
{
HRESULT hr = E_FAIL;
::CoInitialize(NULL);
ITDConnection *connect;
HRESULT hr = ::CoCreateInstance(__uuidof(TDConnection), NULL, CLSCTX_INPROC_SERVER, __uuidof(ITDConnection), (LPVOID *)&connect);
if (connect==NULL)
{
return hr;
}
connect->AddRef();
//OTAClient80.dll api
hr=connect->InitConnection("http://PC-P33774/TDBIN","","");//Making a connection to the an application server
if (FAILED(hr))
return hr ;
//OTAClient80.dll api
hr = connect->ConnectProject("TestDirector_Demo","admin",""); //Making a connection to a project on the server
if (FAILED(hr))
return hr;
IRunFactory *runPointer = NULL;
IList *runFieldList = NULL;
//OTAClient80.dll api
hr = connectionPtr->get_RunFactory ((IDispatch**)&runPointer);
//This line gives an exception..
//OTAClient80.dll api
hr = runPointer->get_Fields(&runFieldList);
//Release the connection and dsiconnect from the project
connect->DisconnectProject();
connect->Release();
::CoUninitialize();
return hr;
}
/* END OF CODE SNIPPET */
When I try to invoke this code from a C# windows application or a console application, the line
hr = runPointer->get_Fields(&runFieldList);
gives an exception as follows:
/* START OF EXCEPTION TEXT */
See the end of this message for details on invoking

Sometimes, I get the error as under:

The value of ESP was not properly saved across function call. This is usually a result of calling a function

There are no errors if I invoke the dll from an MFC application.
The following is the code invoked from the C# application:
DOORSTDLib.TDDOORSApiClass obj = new TDDOORSApiClass();
obj.temp();
Can someone please throw some light as to where can the problem be / what is the solution?

Hi,
with VC C# I tried to connect to several webservices through classes generated by wsdl.exe
when I start my app from VS, I always get the error:
- The request failed with HTTP status 503: Service Unavailable -
but when I start the exe (debug or release) from explorer everything works fine !
Any idee how to make debuging work ?

Hi,
I've created a Form for generating a receipt print out. The Form has controls aligning with a background image (receipt stencil). To have the Form print correctly, the Form is a little large (1006 x 827). I don't display this Form, it's only for printing (loaded at 0 opacity and closed automatically after printing).
The problem is: If the resolution size of the monitor is smaller than the Form size, the Form is reduced to fit. This mucks up the alignment of the controls to the receipt stencil image. Is there a way to stop this from happening.
Thanks,
Ron

how about put your form into a small frame(such as panel) with scroll ability.

Hi,
Do any one know how to freeze some columns in datagrid, like excel does. I would like to see some columns always appear and rest of the columns should appear and disappear with a horizontal scrollbar(like excel freeze).
Thanks in advance.

How do I DeSerialize a file in C++ .NET (e.g. using BinaryFormatter) that was originally created by Serialized in an MFC appliction using CDocument::Serialize?
When trying to do this, I get:
BinaryFormatter Version incompatibility. Expected Version 1.0. Received Version 1684632134.539785569.
Thanks!
|
|
|
|

I doubt that it's possible this way.
CDocument has one format to serialize data and BinaryFormatter has another one. Just stuffing the output from one class into the other one doesn't work. You'll also fail when you let CDocument deserialize a file created by BinaryFormatter.
Both CDocument and BinaryFormatter write some header information into the target file (or try to read it back in), at least containing some kind of version information, but the structure of this header is different, thus the error.
Besides, IIRC CDocument doesn't add type information to its output but I think BinaryFormatter does (but don't quote me here  )
I don't see a chance to achieve this without developing a class to read in a CDocument-generated file manually...

Did anyone work with this thing?
Does anyone know if it works with .NET 2.0 beta 1?
(It's a 300MB download, so I would like to know if it works with .NET 2.0 _before_ downloading it?  )
