hi everyone...
iam working on gridview with checkboxes... iam executing my code without any Errors. i can check/uncheck the checkboxes but not able to delete the row/rows in Grid on Delete_Click().
According to me there is a problem with DeleteRow Function..
So can anyone helpme out in this regard...
thanx in advance..
Here is my aspx.cs Code:
protected void btnDelete_Click(object sender, EventArgs e)
{
// This variable contains the selected rows in the format 1,2,3
string SelectedRows = GetSelected();
// User defined function that calls the stored proc to delete the selected items
DeleteRows(SelectedRows);
}
public static void DeleteRows(string PTittle)
{
SqlConnection MyConnection = new SqlConnection("server=(local);database=BlogDatabase;UID=sa;PWD=meritinfo;");
SqlCommand MyCommand = new SqlCommand("Delete from Posts where PTittle=@PTittle ", MyConnection);
MyCommand.Parameters.Add(new SqlParameter("@PTittle", PTittle));
MyCommand.CommandType = CommandType.Text;
MyCommand.Connection.Open();
SqlDataReader dr = null;
dr = MyCommand.ExecuteReader();
//DataTable Posts = new DataTable();
//DataTable dt = new DataTable();
//dt.Load(dr);
//if (dt != null)
//{
// Posts = dt;
//}
}

sorry yaar ,
still not...
i think in DeleteRow(______), the parameter should empty
couz connection and commands are all ok..
what do u think..
thank for ur help....

Are u sending string of Selected Rows like
Ptittle="1,2,3,5" Like this ???
If like that then ur Delete Query dosen't work
becuase it will be like that
"Delete from Posts where Ptittle=1,2,3,5"
This won't work
Write like that
"Delete from Posts where Ptittle In ("+@Ptittle+")"
mein Salah doonga ki
Debug the Code and see What is the Command text
|
|
|
|
|
see yaar.
at MyCommand.ExecuteNonQuery ....SqlException raised--->Incorrect Syntax near ','
command text=
Delete from Posts where PTittle In (,)
|
|
|
|
|
i am trying new code now....here i can bring all checkbox selected fields PTittle value in a string gvID's...and passing to delete command...
but at ExecuteNonQuery() the Error raised that Incorrect Syntax near gvID's value...(for eg:Political Influence on Students is the value in
the string contains PTittle Values Collection...saying Syntax Error near Influence....

Pls be so kind to use google with the query: "log4net"...
|
|

|

I think you can get details using WMI. but why in Asp.net ?
|
|
|
|

Is there any build-in function available in .Net framework, which accepts some number and returns a string
value equalent to the number?
[For ex: ReturnEqualentWord(int num); while passing, 5, it should return me Fifth,while 12, it should result twelve or twelvth.]
Muthu

.Net framework doesn't provide this but you can make your own custom function.

I am trying to do file handling through jscript. While trying to create an object, it produces an error saying,

Looks like the ActiveX component could not be loaded...
Pls provide the code to get a more specific answer.
|
|
|
|
|
function callWriter(){
var fileSysObj = new ActiveXObject('Scripting.FileSystemObject');
var fileObj = fileSysObj.OpenTextFile("C:\\FromJs.txt",2,true,0);//2-overwrite,true-create if not exist,0-ASCII
fileObj.write('File written from Javascript');
fileObj.close();
}
so when i call the above function the error msg is thrown. should i do any thing in browser settings?
Muthu

Hi Muthu,
first of all you should check the browser settings, if ActiveX is enabled etc.
If this doesn't help, it is possible that the DLL containing the ActiveX is not registered properly. (but here it seems to be a system dll, that
's why it should be registered already).

how to use AL(Assembly Linker.exe) in command prompt. I have a dll called sample.dll
now i have to put it in GAC(Global Assembly Cache]. I tried with possible arguments like
AL sample.dll
AL /out:sample.dll
AL /out:Program.exe /link:sample.dll
i couldn't attain a solution.
Could any one tell me how to use it, with sample parameters?
Note:AL is used to create shared assemblies and it includes our assembly in WINNT\assembly folder of local machine.
