Adding assembly reference Problem - C# Discussion Boards

Re: how to include header file in C# project [modified]

Hi @all,
thank you for your support. Finaly we decided to make a 'Global Assembly Info' class. This class will be added to all c# projects (as a link), which need to use global versioning infos. This class is defined as static and has only public static constants:
internal static class ProductInformation { [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1823:AvoidUnusedPrivateFields")]
public const String Product = "Product name...";
...}

This constants are used to modifie the assembly-versioning attributes in the particular c# AssemblyInfo.cs like this :
(using namespace of 'Global Assembly Info' class...)
[assembly: AssemblyProduct(ProductInformation.Product)]
[assembly: AssemblyFileVersion(ProductInformation.Major + "." + ProductInformation.Minor + "." + ProductInformation.SR + "." + ProductInformation.Build)]
...

The 'Global Assembly Info' class will be filled manually, and not from the 'Versioning.h' as it was planned at the beginning.

It should be one click, try changing

saveFileDialog2.ShowDialog()

to saveFileDialog2.ShowDialog(this)

Which shows the dialog box as a modal child of the current form, it might be that or you may have to make sure that Main in your project has an STAThread attribute applied to it (if you forget this I know that the FolderBrowserDialog does wierd things, maybe the SaveFileDialog class is the same).

Regarding the saving of Excel files you'll need a component or class that can read and write Excel files (you could use the COM Excel component or use a managed one such as Aspose.Excel[^] but you'll have to buy that I think.

You know you're a Land Rover owner when the best route from point A to point B is through the mud.

I want to add a reference to a dll created by vb6 but it always raise the following error when i try to add it:

this is not a valid assembly or com component. only assemblies with extension 'dll' and com components can be referenced. please make sure of that the file is accessible, and that it is a valid assembly or com component.

can you help ?

You can only add references to .NET assemblies. If you want to add a reference, you need to either write a Managed C++ wrapper around the VB6 dll or make the VB6 DLL a COM component.

In case you didn't know, you can always use P/Invoke to call functions in DLLs without referencing them when compiling. If you are calling only a few functions in the DLL, I'd suggest you use P/Invoke, as it is much simpler, especially if the functions don't pass around any complex data structures.

This is a code sample copied from pinvoke.net[^] for the standard MessageBox Win32 API function.

class XYZ
{
...
[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern uint MessageBox(IntPtr hWnd, String text, String caption, uint type);
}

You can then use MessageBox just like any other static function in that class (XYZ.MessageBox(...))

Well, you've added a property to Status yourself, what exactly are you trying to do?

How to obtain DWG file from OLE object?

sahmad5764-Jun-06 23:50

4-Jun-06 23:50

Hello All,

I am writing a console based application using C# in which I want to implement a feature which could extract OLE objects from Word documents and then save it in DWG file format. The OLE objects exist in Word documents are in the form of AutoCAD Drawing i.e. once I double clicked the Object; the system opens it in AutoCAD.

Currently I have accessed the OLE object through “Word.InlineShape” object by using Word Interop API but couldn’t find any way to save it in AutoCAD supported DWG file format. Does any one have any idea how can I obtain a DWG file through the OLE object?

Although I have extracted the OLE object in a BMP file by using “Selection.EnhMetaFileBits” property but the requirement is to be saved in DWG file format. I’ll be grateful if any one could help.

Thanks in advance!

Hi,
I am getting Cryptographic Exception while calling FlushFinalBlock method of CryptoStream after decrypting a buffer. Here is my code that decrypts the buffer....

des.BlockSize=blockSize;
des.Key=kDESKey;
des.KeySize=64;
des.Padding=PaddingMode.PKCS7;
des.Mode=CipherMode.ECB;

ICryptoTransform cryptoTransform=des.CreateDecryptor();

byte[] outputBuffer=new byte[cipherTextBytes.Length];
cryptoStream.Write
(cipherTextBytes,0,cipherTextBytes.Length);
cryptoStream.FlushFinalBlock();
outputBuffer=mem.ToArray();
cryptoStream.Close();

As soon as i call FlushFinalBlock it throws Cryptgraphic exception with message BadData. Please help me to solve this problem...

To deploy an asp.net 2.0 site onto the live machine, should it have IIS as well as .net 2.0 framework?
Does this mean that I have to instal VS2005 on the LIVE machine first before deployment?
Basically what should be installed on the LIVE machine please?
