I am using a 3rd party DLL that uses the J# runtime. If J# isnt installed, i get a FileIO exception. I want to be able to check when my program starts up if J# is installed, I think the best way is to load the assembly, if its found, then carry on, if not, notify the user.
I tried:
Assembly.Load("vjslib"); and Assembly.Load("vjslib.dll"); but both throw not found exceptions.
The below works fine, but that means the path is hard coded. Is it possible to get the DLL's location dynamically?
string path = "C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\vjslib.dll";
Assembly assembly = Assembly.LoadFile(path);
Regards,
Gareth.

Just a thought, try if you can write a small search routine and search the dll in %systemroot%\\Microsoft.NET\\
If J# runtime is installed is it definite to have the dll in C:\WINDOWS\system32\? If yes use %systemroot%\\system32\\vjslib.dll
string path = "%systemroot%\\Microsoft.NET\\Framework\\v2.0.50727\\vjslib.dll";
Assembly assembly = Assembly.LoadFile(path);

KSuthar,
That still doesn't get around the problem of having a hard coded path.

Since DOC node doesn't have child, you only need one loop which iterates the child nodes of BIBLE. See the following code
for (int i = 0; i < bNode.ChildNodes.Count; i++)
{
XmlNode node = bNode.ChildNodes[i];
string strElement = node.Name;
if (strElement.ToLower().Trim() == "doc")
{
string strDocClientID = node.Attributes["CLIENT_ID"].Value;
string strDocMatterID = node.Attributes["MATTER_ID"].Value;
string strDocNumber = node.Attributes["DOCNUMBER"].Value;
string strDocName = node.Attributes["DOCNAME"].Value;
}
}This can be done in a better way if you use XPath.

Get a XmlElement and SelectSingleNode of that, instead of the XmlDocument. I am not sure why it is returning SECOND, I am beginner, I had this information thought of sharing, might help you, Let me know if it do help.
XmlDocument doc = new XmlDocument();
doc.Load(strFullPath);
XmlElement root = doc.DocumentElement;
XmlNode bNode = root.SelectSingleNode("BIBLE");
string strBibleClientID = doc.DocumentElement.GetAttribute("CLIENT_ID");
string strBibleMatterID = doc.DocumentElement.GetAttribute("MATTER_ID");
string strBibleDocNumber = doc.DocumentElement.GetAttribute("DOCNUMBER");
for (int i = 0; i < bNode.ChildNodes.Count; i++)
{
XmlNode bibleNode = bNode.ChildNodes[i];
int intElements = bibleNode.ChildNodes.Count;
for (int x = 0; x < intElements; x++)
{
string strElement = bibleNode.ChildNodes[x].Name.ToString();
if (strElement.ToLower().Trim() == "doc")
{
string strDocClientID = bibleNode.ChildNodes[x].Attributes["CLIENT_ID"].Value;
string strDocMatterID = bibleNode.ChildNodes[x].Attributes["MATTER_ID"].Value;
string strDocNumber = bibleNode.ChildNodes[x].Attributes["DOCNUMBER"].Value;
string strDocName = bibleNode.ChildNodes[x].Attributes["DOCNAME"].Value;
}
}
}

Hello there !
I'm developing a Windows appliciation that involves so called "Transparent Controls". As you would probably know, the only ( as far as i know ) way to achieve a fully transparent control in C# is to add the so called "Transparent style" to your control ("WS_EX_TRANSPARENT"). There are numerous articles how to achieve this and the method is ALMOST always one and the same:
protected override CreateParams CreateParams
{
get
{
CreateParams cp=base.CreateParams;
cp.ExStyle|=0x00000020;
return cp;
}
}
protected override void OnPaintBackground(PaintEventArgs pevent)
{
}
And that works fine! ( well .... at least all say that ..... and all the articles say so ), but am i missing something or that method has SOME SERIOUS problems that nobody can see ?
For example the Z-order. The following piece of code creates simply a transparent control that draws a line accross itself with a random color:
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
namespace WindowsApplication16
{
public class HrisTranspControl : Control
{
private Pen _drawingPen;
public HrisTranspControl()
{
Random rnd = new Random();
this._drawingPen = new System.Drawing.Pen(new System.Drawing.SolidBrush(System.Drawing.Color.FromArgb(rnd.Next(0,255),rnd.Next(0,255), rnd.Next(0,255))),5);
}
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x00000020;
return cp;
}
}
protected override void OnPaintBackground(PaintEventArgs pevent)
{
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
e.Graphics.DrawLine(_drawingPen, new System.Drawing.Point(0, 0), new System.Drawing.Point(this.Width, this.Height));
}
}
}
And so ... when u put few "line controls" on top of each other the Z-ORDER goes to hell. You can't change it, its not corrent and it changes randomly each time u select a random "line control".
I've tried A LOT of methods to fix that ( changing the z-order in background, repainting the actual background because i think its because the background is not drawn ... and so on ). None works. I'm out of ideas and the worst part is i've almost finished the application and right in the end i realize that bug and it kills me.
Please help !!!
http://xs135.xs.to/xs135/09015/z-order696.jpg.xs.jpg[^]
The "line controls" were added in the order shows 1,2,3 , but the Z-order appears to be different ( 1,3,2 ). In the current case "bring to front" , "send to back" doesnt change the Z-ORDER

I think your problem stems from a misunderstanding of the meaning of WS_EX_TRANSPARENT. It has nothing to do with visual transparency; it makes a window 'transparent' to mouse clicks. In other words, the click goes through to the window underneath. If you're trying to use the mouse to select such a window you are bound to get confusing results! You probably don't need that style at all.

hello
I'm trying to upload to database object of type byte[], currently using C#/byte[]/DbType.Binary (implementation in progress) and database column "varbinary(MAX)" with SQL Server. But I then realize this is SQL Server specific and would really prefer something that's database independent.
Also haven't tried the part with IDataParameter.DbType = DbType.Binary yet, not sure if this is right because I was reading an article - varbinary goes with SqlDbType.VarBinary, not sure if DbType.Binary is correct at all.
Thanks
dev

System.Data.DbType and corresponding provider specific DbTypes are linked so using the System.Data.DbType should match correcly to the corresponding DbType.
However, if you're making this database independently, have you considered using OleDbConnection against all databases.

I want to use C# to save the changes made to an existing excel file. The path of the excel file is fixed and it can be assumed that the file is opened in an excel window from before. All I want to do is write a program that periodically saves whatever changes were made to the file (in the excel window) since it was last saved. I have tried sending the Ctrl-S windows message to excel and also tried playing around the Microsoft.Office.Interop.Excel namespace, but to no avail. Is there a way to do this that anyone is aware of? I am using Office 2007 but a solution for Office 2003 or 2002 will also be of help to me.

When the Excel is opened then you have to attach your application to existing Excel process. The Save method works for me.
|
|
|
|

Can you write some sample code to attach an object of Microsoft.Office.Interop.Excel.Application to an already existing excel.exe application?

YourDataGrid.SelectedRows[0].Index
First check if YourDataGrid.SelectedRows.Count > 0

This is how to get selected row from DataGridView in .NET 2.0
Make sure there’s a single cell that is currently selected
Get current row index using {datagridview instance}.CurrentCell.RowIdex
Get the selected row using {datagridview instance}.Rows({current row index}).Cells({zero based index}).Value
Here’s the sample code :
Dim crow = DataGridView1.CurrentCell.RowIndex
dim txt as string
Try
txt = DataGridView1.Rows(crow).Cells(0).Value & ” || ”
txt = txt & DataGridView1.Rows(crow).Cells(1).Value & ” || ”
txt = txt & DataGridView1.Rows(crow).Cells(2).Value
MessageBox.show (txt)
Catch ex As Exception
‘ do nothing
End Try

Hi,
I want to change some looking of some control.
For example - i want to change some Button to be circle.
How can i do it ?

You can handle the paint event and do your own drawing. This[^] was my first hit when I searched.
|
|
|
|
|
Alternatively, you can do something like I did in this[^] reply if you don't want to handle the drawing of the entire control, this was for a pictureBox but works for other controls too.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

Dear All,
I have a network program which has client and server.
The server will be listening the client at a specific port and IP address.
The client is connecting and writing the data to the server.
When the client connection is established the server will continuously listen the client and gets the packet sent by it.
When the time goes on the server takes up lots of memory in RAM and the CPU utilization goes to 80 to 100%.
The connection used was TCP.
Can any one tell me why this happens.
Best Regards,
M. J. Jaya Chitra

Probably because of incorrect usage of threads. Try to use asynchronous fashion methods (BeginXXX,EndXX) which is very efficient. Hard to tell more without seeing the code.

looks like you are using while loop, instead of thread.
