Where are you reading the string from? Do you know what encoding is used for the string?
Strings in .NET is Uncocde, which supports virtually every character on the planet. (Characters that are not supported (yet?) are stuff like the Klingon alphabet and Tolkien runes...)
Strings are usually not stored as 16 bit Uncode, so some kind of encoding is used when they are stored. You have to know this encoding to be able to correctly decode the string into Unicode.
Some common encodings are 8 bit Unicode (UTF8) and Latin 1. ASCII encoding only support characters 0-127, so that is not suitable for what you are doing.

When any kind of new project in Visual Studio is opened, whether its a console based app. or a windows based one.....'.cs' file opens up with a standard set of included namespaces.
The following is a snippet of a newly opened WindowsApplication
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
Here the following namespaces are included
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
Is it possible to edit this default inclusion of namespaces.

I dont have VS 2005, but in 2003 digging around in the folder C:\Program Files\Microsoft Visual Studio .NET 2003\VC# shows many templates used by the wizards in VS. I know that changing these files will affect the template used when, for example, you shoose to add a new class.
Take a backup before changing anything in these dir's

i have a combo box. i want it to display all items in a particular folder and subfolders with the extension *.jpg and when you clik on one it will change the image in a picturewall picturebox to that image. Also if format is invalid, a messagebox will display saying ''invalid file format'' and not load the image. How would you do this
In the end we're all just the same

Hello everyone,
After I publish my C# VS2005 application (to be installed from CD-ROM), the crystal reports in it will not load, but if I run the application from debug, everything works fine. Does anybody know what's going on? Thanks a lot.
Best regards,
JC

Problem solved!
It was pathetically simple... All I had to do was to set the reports file property "Build Action" to "Content". Now everything is ok. Thanks a lot!

Hello,
As I'm programming in good old C, Win32 API, I'm looking for the equivalent of the OpenFileDialog().
What I'm looking for is the replacement of
OpenFileDialog openFileDialog1 = new OpenFileDialog();
By something like
DialogBox(hinst, "MyBoxDB", hwnd, (DLGPROC) DialogFunc);
or
hHelp = CreateDialog(hinst, "HelpDB", hwnd, (DLGPROC) HelpFunc);
ShowWindow(hHelp, SW_SHOW);
I'm not using any visual devellopment environments. Just a texteditor, a resource compiler and g++.
A static library, containing something like the OpenFileDialog(), would also be nice. As long as it's possible to implement it in a plain C program. As I'm using g++ in stead of gcc, It's no problem to make use of C++.
The guys from MS didn't cooperate; maybe someone in here knows the answer?
Thank you,
Frits aka TWW

Do you think the C# forum is the correct place for this question?
Anyway, the OpenFileDialog is basically a wrapper around the open file dialog in the commdlg.dll, so it could be a good idea to investigate into the GetOpenFileName() export of this dll.

The problem is that my question has to do both with C# and C. It's always in between two languages.
Should a question about the translation form an English word to a Dutch word be posted on English or a Dutch forum?
At least I’ve now got a direction where I can look.
Thank you very much.
Regards,
TWW

Problem is solved!
Link against comdlg32.lib
The stuff like
openFileDialog1.InitialDirectory = "c:\\";<br />
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";<br />
openFileDialog1.FilterIndex = 2;<br />
openFileDialog1.RestoreDirectory = true;
Is "translated" into something like
OPENFILENAME browse;<br />
char szFile[260];<br />
ZeroMemory(&browse, sizeof(browse));<br />
browse.lStructSize = sizeof(browse);<br />
browse.hwndOwner = hwnd;<br />
browse.lpstrFile = szFile;<br />
browse.lpstrFile[0] = '\0';<br />
browse.nMaxFile = sizeof(szFile);<br />
browse.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";<br />
browse.nFilterIndex = 1;<br />
browse.lpstrFileTitle = NULL;<br />
browse.nMaxFileTitle = 0;<br />
browse.lpstrInitialDir = NULL;<br />
browse.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
And the function call
if (openFileDialog1.ShowDialog() == DialogResult.OK)
is "translated" into
if (GetOpenFileName(&browse)==TRUE)
Regards,
TWW
It's just finding the right words and the result is the same.

I can instantiate a COM object in VC++ without any problem.
But when i call one function exported by the COM object i

I think the most common problems when using COM objects in an ASP.NET environment are security-related.
You can use the method without problems when you write a test application because this test application is executed under your user account.
Your webform (and thus all COM objects you create/use there) is usually executed under the ASPNET account, so the COM object might not behave as expected.
Check you COM class if it has access to everything it needs, even if it's not executed under your user account.

I have a problem where I'm developing a WinForms application. I have one set of controls, eg., accepting user details that I need to show on all my forms.
What would be the easiest way to club all these related controls into a class, and show it on all pages by just doing a Form.Add control or something like that?
TIA,
Jaffar

Hi
You could create a UserControl with the common elements on it, then just add this control to your forms.
