Another way (I'm not too keen on this but in some ways is better) is to take control of the Application thread yourself.
The reason the application closes when your initial form does is because of the Application.Run(new Form1()); in the Main method of Program.cs.
If you show the form yourself before this line and then just call Application.Run(); the application then won't close until Application.ExitThread() is called.
This method is static so can be called from anywhere. Just make sure it is definately called from any place that should be able to close the program.
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)

You need to look into using the args that is passed to the main function.

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.

Hi,

Any thoughts please?
Thanks

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?

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
