Sir,
Your first statement was right that I m having textbox outside to that of datagridview.
You gave the code which was in ASP.NET but,I m working on C# Windows.
Even I succeeded in adding checkboxes at runtime on textchange event of external checkbox on your behalf....Thanks.
But, now I m quering about how will I get the appropriated row record on clicking respective checkbox on the row ? Is there any event about databinding events to succeed further?
I want to check it for furher process.
Please help.
awaiting.................

You can add a COLUMN of checkboxes, you cannot add a chackbox to a single row. I use the following:
DataGridViewCheckBoxColumn oDGC = new DataGridViewCheckBoxColumn();
oDGC.HeaderText = "Sel";
oDGC.Name = "Sel";
oDGC.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
oDGC.FlatStyle = FlatStyle.Standard;
oDGC.CellTemplate = new DataGridViewCheckBoxCell();
oDGC.CellTemplate.Style.BackColor = System.Drawing.Color.Beige;
oDGC.ThreeState = false;
oDG.Columns.Insert(iCol, oDGC);
Never underestimate the power of human stupidity

Hello,
We have choosen to use Microsoft Enterprise Library in a project that I am involved with. We wan't to write messages to the windows event log with Enterprise Library. I have succeseeded to with that but I have a question with information regarding the stacktrace.

I wan't to know how to write only the message to event log. I don't wan't to see the full stacktrace.

How did you checking the use id and password? Where is the code? Did you check with String.Equal() or what ?

|

this is the Code I am using
SqlConnection Con1 = new SqlConnection("server=.;database=ab;uid=sa;pwd=max");
Con1.Open();
SqlCommand cmd1 = new SqlCommand("select UserName,Password from mads Where Username= '" + usrtxt.Text + "' and Password ='" + passtxt.Text + "'", Con1);
SqlDataReader dr = cmd1.ExecuteReader();
dr.Read();
if (dr.HasRows == true)
{
prj = new Project_Details(usrtxt.Text);
prj.Show();
}
dr.close;

SQL is case insensitive. You have to force SQL to turn on the case sensitivity for the select query. Just add the following clause with your select query:
COLLATE SQL_Latin1_General_CP1_CS_AS
Use COLLATE SQL_Latin1_General_CP1_CI_AS for case insensitivity.
It can solve your problem.

If this is your live code, Please be careful about SQL Injection.

Check out the following code:
if (string.Compare("hello", "Hello", false) == 0)
{
//do whatever you wish
}
The third parameter makes the string comparison case sensitive.

Hi, i have a problem about threads with windows forms.
When users's sessions ended, i want to show a dialog box to inform them to relogin and then to show the relogin form.
It was ok until i use threads in some forms to improve performance.
When a thread reveices a session error, it shows the relogin form. Actualy i use invoke on the main thread.
But while the dialog form is shown, another thread can make a service call and receive the same session error and so tries to show the same relogin form. But it is clear that only one instance of relogin form must be shown at the same time. So i have to use a locking mechanism. But since the thread that shows the dialog box is the main thread, this causes the main thread enter wait state. So the application freezes.
public bool Relogin() {
Interlocked.Increment(ref waitingThreadCount);
event1.WaitOne();
if(this.loginResult == null) {
loginResult = ReloginForm.Show();
}
Interlocked.Decrement(ref waitingThreadCount);
if(waitingThreadCount == 0) {
loginResult = null;
}
event1.Set();
return loginResult.Value;
}

Hi,
I have CrystalActiveXReportViewerLib11_5.dll for my application. I have used a typed Dataset. In this DataSet there are two DataTables DataTable1 and DataTable2. DataTable1 is used for main report and DataTable2 is for SubReport. When i set DataSource for both DataTable i got a problem. For only one dataTable it is ok.
Any help for this problem is appreciated. It is urgent. My code is like this:
DataTable dtt1 = LoadDataTable();
DataTable dtt2 = LoadFriendDataTable();
CRAXDDRT.Application crxApp = new CRAXDDRT.Application();
CRAXDDRT.Report crxReport = new CRAXDDRT.Report();
crxReport = crxApp.OpenReport(Application.StartupPath+"\\rptHouseLandTaxLetter.rpt",null);
crxReport.Database.Tables[1].SetDataSource(dtt1, null);
//crxReport.Database.Tables[2].SetDataSource(dtt2, null); //error occurred here
this.crViewer.ReportSource = crReport;
this.crViewer.ViewReport();
private DataTable LoadDataTable()
{
CrystalReportTest1.DataSet1.DataTable1DataTable dtReport = new DataSet1.DataTable1DataTable();
foreach (DataRow dr in dt.Rows)
{
dtReport.Rows.Add(dr.ItemArray);
}
return dtReport;
}
private DataTable LoadFriendDataTable()
{
CrystalReportTest1.DataSet1.DataTable2DataTable frienddt = new DataSet1.DataTable2DataTable();
foreach (DataRow dr in dt.Rows)
{
frienddt.Rows.Add(dr.ItemArray);
}
return frienddt;
}

Hi,

Yes, I did register control using regsvr32.exe
I have been using a lot of ocx control so far and this is the only one give me that error.
Thanks,
Brandon

Assuming your control got registered successfully, try clearing all the files in obj/debug or obj/release. Now try to add the control again.
If you have problem in registering control using regsvr32, use dependency walker and profile regsvr32 by specifying the dll to be registered.

Navaneeth,
I have tried many time to delete the files in obj and debug folder but the error is still there.
I am not sure I have problem using regsvr32 or not since I have used to register a lot of controls so far. All works fine, except this control ecgraph3D.ocx
How can I use dependency walker and profile regsvr32 ?
Many thanks,
Brandon

The problem is obviously going to be specific to the control.
Does the control come with any samples ? Do they work ?

Christian,
The control comes with visual basic 6 example and it works on my machine. This company has ecgraph.ocx and it works on my visual studio 2005. Now they just have ecgraph3D.ocx as their new product but this control doesn't want to work on my C# 2005
Thanks,
Brandon

So the VB6 sample you have is for the new control, or the old one ? If that works, then the issue is somewhere in how you're importing the file.

Christian,
The VB6 example is for the new control. I just try to add control on different computer and error is the same.
I am not sure what is causing this problem.
Any further help, please let me know.

Hello All,
I hope someone can help. I have a dataGridView populated with data, I have added a dataGridViewComboBoxColumn. The dataGridViewComboBoxColumn is populated per row. That all works great. The issue I am having is getting the value of a dataGridViewComboBoxColumn Cell.
The last thing I tired is:
DataGridViewComboBoxCell cell = dataGridView1[cntR, cntC] as DataGridViewComboBoxCell;
string val = cell.ValueMember.ToString();
string val2 = cell.Value.ToString();
Which always returns "" for both.
Any help would really be great.
