I have written code for report in Form_Load event handler as under:
System.Data.SqlClient.SqlDataAdapter adapter = new System.Data.SqlClient.SqlDataAdapter("Select * From Customers",
"server=pc1;database=northwind;trusted_connection=true");
System.Data.DataSet ds = new DataSet();
adapter.Fill(ds, "Customers");
CrystalDecisions.CrystalReports.Engine.ReportClass rpt1 = new CrystalDecisions.CrystalReports.Engine.ReportClass();
rpt1.SetDataSource(ds.Tables["Customers"]);
CrystalDecisions.Windows.Forms.CrystalReportViewer rptviewer = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
rptviewer.Dock = DockStyle.Fill;
this.Controls.Add(rptviewer);
rptviewer.ReportSource = rpt1;
but it gives me the following error:
Unable to find the report in the manifest resources. Please build the project, and try again.
Can someone help how to generate report in this way?
Thanks for consideration

hi all,
i have a windows form lets say 'myform'.
i check on myform's load if there is a previous instance of 'myform' running or not.
> if a previous instance runs, then i display an error message and close the secondly opened copy.
but after closing secondly opened instance, i dont know howto maximize the first copy of 'myform' which was minimized on taskbar ?
do u know howto maximize & bring to front the previous myform or at least to blink it like msn messenger ? (when a message received)
thanks in advance,
bye.

Hello Frieds,
I just want to ask you that, How to split the string by another string.
Take ex.-

string delim = "***";

split2 = 3*2**5
Thanks in Advance.

Try this:
string[] Parts = tosplit.Split("***", StringSplitOptions.RemoveEmptyEntries);
|

Firstly Thanks for your response.
You have suggested "StringSplitOptions".
But i think it is not in the framework-1.1
Can you suggest any other solution.

You're right, it's new in Framework 2.0.
Perhaps you can use IndexOf("***") in combination with Substring.

Use a regular expression:
Regex re = new Regex(@"\*\*\*");
string[] splits = re.Split(tosplit);

I know dictionaries don't accept duplicate keys, but hashtables are inherent within dictionaries. If the answer is yes, then what data structure could I use?

One possibility is a hashtable whose values are ArrayLists list of values. When you try to add a duplicate key, append the key's value to the existing list.

Hashtables dont except duplicate keys, and im not sure there is a class that would allow you to store items in order and allow duplicated.
U could try deriving a new class from the HashTable table and replacing the comparer property with a new one that will allow you to add duplicates.

I have a simple question. If I have a form with some buttons inside, how can I recieve keyboard messages for the arrow keys? If I hook the KeyDown event of the parent form, I recieve notification just fine, until I press one of the buttons, at which point the event is no longer triggered; the focus jumps through tab order instead.

Im not a 100% sure on this, but the form has a KeyPreview property. This passes the keyboard presses to the form before passing to the active control.
|
|
|
|
|
Yes I've got it set already, but it doesn't help!

Have u tried overriding the DefWndProc (or WndProc) methods to detect the key presses there.

Hi. How do I created an update installer. Say I already installed the whole app on the client machine, made a few changes, no I just want to update their app, I don't want to remove the whole app and re-install.
Thans in advance
He who laughs last is a bit on the slow side

The .Net setup wiz allows you to 'update' the app. When you change the version number, the product gui will get updated, while the upgrade gui remains.

You can search in google for "VirtualDub".
There is also with source code in it. But in C++.

Hi
What is the best way for remove item from System.Collections.ArrayList (most rapid) :
Remove(object Obj) or
RemoveAt(int Index)
Thank
|
|
|
|
|
What dou you mean with the "best way" ?
If you have the object, the best way is Remove(object obj);
If you have the index, the best way is Remove(int index);
|
|
|
|
|
RemoveAt(int Index) faster, look at the following code of Remove(object Obj):
<br />
public virtual void Remove(object obj)<br />
{<br />
int num1 = this.IndexOf(obj);<br />
if (num1 >= 0)<br />
{<br />
this.RemoveAt(num1);<br />
}<br />
}<br />
As you can see Remove(object obj) actually calls to RemoveAt(int Index)
|
|
|
|
|
|
RemoveAt() is safer in case the ArrayList contains duplicate objects.
