Why not add a System.Windows.Forms.HelpProvider by dropping one onto your form, set its HelpNamespace to the .chm file you want to open and then in your form's properties, set the HelpKeyword and HelpNavigator properties?
the Visual Studio 2005 documentation has an example in C# for the HelpProvider class.
Good Luck!

You've already asked this question on the SQL forum.
What has this got to do with C#?

I didn't try it, but this should be it:
private bool GetTables()<br />
{<br />
try<br />
{<br />
SqlConnection dataConnection = new SqlConnection();<br />
dataConnection.ConnectionString = ConnectionString;<br />
dataConnection.Open();<br />
SqlCommand dataCommand1;<br />
SqlDataReader dataReader1;<br />
<br />
dataCommand1 = new SqlCommand();<br />
dataCommand1.Connection = dataConnection;<br />
dataCommand1.CommandText = "SELECT Name FROM [Master].[dbo].[sysdatabases]";<br />
dataReader1 = dataCommand1.ExecuteReader();<br />
<br />
while (dataReader1.Read())<br />
{<br />
Console.WriteLine(dataReader1.GetValue(0));<br />
}<br />
dataReader1.Close();<br />
dataCommand1.Dispose();<br />
dataConnection.Close();<br />
<br />
return true;<br />
}<br />
catch (Exception ex)<br />
{<br />
Console.WriteLine("Error - Tables " + ex.Message);<br />
return false;<br />
}<br />
}

Hi guys,
I need some help pretty urgently please...
I'm using a console application (C#) to clear emails out of the Deleted Items folder on a outlook app running on a server - keeping the latest 300 mails. That part works fine - I created the application class, namespace (MAPI), folder and explorer for this instance - the first problem I have is, clearing the Deleted Items folder works, but how do I move from the Deleted Items folder to a user created folder called 'test'?
Secondly, how do I move between multiple mailboxes within the same outlook instance?
Any help would be greatly appreciated!
Thanks!

Hi,
I'm trying to write the data in the dataset to Excel. Following is my code snippet:
Excel.Application xlApp;
Excel.Workbook xlBook;
Excel.Worksheet xlSheet1;
public void ToExcel(DataSet M_Dataset)
{
object oMissing=System.Reflection.Missing.Value;
try
{
DateTime dt1=DateTime.Now;
string GetCurrentDate="";
string strFilePath = string.Empty;
GetCurrentDate=dt1.ToString("ddMMMyy");
//Start Excel, and then create a new workbook.
xlApp = new Excel.ApplicationClass();
xlBook = xlApp.Workbooks.Add(Missing.Value );
xlSheet1 = (Excel.Worksheet)xlBook.Worksheets.get_Item(1);
xlSheet1.Name = "FinalBonds_"+"_"+GetCurrentDate ;
EventDel_BeforeBookClose =new Excel.AppEvents_WorkbookBeforeCloseEventHandler( BeforeBookClose)
xlApp.WorkbookBeforeClose += EventDel_BeforeBookClose;
//Add an event handler for the Change event of both worksheet objects.
EventDel_CellsChange = new Excel.DocEvents_ChangeEventHandler( CellsChange);
xlSheet1.Change += EventDel_CellsChange;
System.Data.DataTable xlsTbl=M_Dataset.Tables[0];
int ColumnIndex=0;
foreach(DataColumn col in xlsTbl.Columns)
{
ColumnIndex++;
xlSheet1.Cells[1,ColumnIndex]=col.ColumnName;
//((Range)xlSheet1.Cells[1,ColumnIndex]).EntireRow.Font.Bold=true;
//((Range)xlSheet1.Cells[1,ColumnIndex]).Columns.AutoFit();
}
int rowIndex=0;
foreach(DataRow row in xlsTbl.Rows)
{
rowIndex++;
ColumnIndex=0;
foreach(DataColumn col in xlsTbl.Columns)
{
ColumnIndex++;
xlSheet1.Cells[rowIndex+1,ColumnIndex]=row[col.ColumnName];
}
}
errMessage="Sucessfully written records in Sheet 1.";
//cfg.LogMessage(errMessage);
strFilePath = @"C:\Projects\LiquidCreditChains\LIQReports\FinalUniverseBonds.xls";
xlBook.SaveCopyAs(strFilePath);
}
catch(Exception ex)
{
string strErrMsg = string.Empty;
strErrMsg = ex.Message;
}
}
I'm getting the error message as "Exception from HRESULT: 0x800A03EC.". I don't know what it means. Please help. Please let me know if you require further information to resolve the issue.
The dataset contains 40 columns and 4500 rows.
Thanks,

Good Afternoon
I have a button sitting on form1 and i would like form2 to trigger that button
How do I go about doing that:
in form1 i just say button1.PerformClick();
and it works however I would like to call the event using form2
|
|
|
|
|
Assuming that form2 has a reference to form1, then you can simply create a public method to perform the click.
public void ClickButton() {
button1.PerformClick();
}
form1.ClickButton();
Take care,
Tom

Hello,
I am using config file in C# form application. I have provided UI which takes the data form user and on request saves the data to the Properties.Settings.Default.MyVal
The problem is that internally(while debugging the application i saw) it knows that the particular data has been modified and reads the modified data but these changes are not reflected in app.config file.
How should i save the data to the Properties.Settings.Default.MyVal file so that it reflects to the app.config file exacly.
Thanks.

I had a couple of thoughts on this, though I'm not an expert:
When you are running in debug mode, I thought it wrote changes to a temporary config file in the Debug directory rather than in the project directory. You might check that.
Also, how are you writing out application-scoped settings? I know that user-scoped ones can be assigned, but I thought application ones were read-only. I know you can read the XML yourself and do it, but I *thought* only user settings were writable.
Good Luck!

There's at least one article on this site, I used it to handle COM communicaton in .NET 1.1 ( where I needed an external dll, but I think 2.0 has it built in )
