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?

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!

DESCryptoServiceProvider des=new DESCryptoServiceProvider();
des.BlockSize=blockSize;
des.Key=kDESKey;
des.KeySize=64;
des.Padding=PaddingMode.PKCS7;
des.Mode=CipherMode.ECB;
ICryptoTransform cryptoTransform=des.CreateDecryptor();
MemoryStream mem=new MemoryStream();
CryptoStream cryptoStream=new CryptoStream
mem,cryptoTransform,CryptoStreamMode.Write);
byte[] outputBuffer=new byte[cipherTextBytes.Length];
cryptoStream.Write
(cipherTextBytes,0,cipherTextBytes.Length);
cryptoStream.FlushFinalBlock();
outputBuffer=mem.ToArray();
cryptoStream.Close();
mem.Close();
return removeLength(outputBuffer);
As soon as i call FlushFinalBlock it throws Cryptgraphic exception with message BadData. Please help me to solve this problem...

Hi,
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?
Thanks
|
|
|
|
|
hi,
ofcourse you need iis,its not nessary to install VS2005. you can download net framework 2.0 redistributable and install in live machine.
if the live machine has autoupdate on for windows update,it will be there.
you can verify it in IIS properties.
good luck
Where there is a will,there is a way.

Actualy want to put the values of DataGrid into a DataTable.how is it possible.plz help me.

Hi foysal cool,
I think you want to build the data table with only selected data's from datagrid ok, if it is true then you have to get the datagrid row(cell's) value by travelling through whole datagrid.
To get the datagrid cell value:
Create obj for datagrid item for that datagrid then get the value of that particular row.
foreach(DataGridItem dgi in DataGrid1.Item)
{ string name=dgi.cells["column name1"].ToString();
............
..........
}
Best Regards.,

lets say datatable1 and datagrid1 ...
put the the datasource for datagrid1 = datatable
then whatever you change in the grid will reflect
on the datatable1 , then use datarow.rowstatus or
datatable.getchanges to get all the changed rows
