What is the procedure for adding crystal report Version 10 Licence, Product key or registration key in order to aid its deployment
|
|

|
|
I want to fill a combo box with values from a field in a table. Hod do I?
|
|
|
|
|
Select the values from the DB, set the datatable to be the datasource and set the displaymember to be the name of the column.

Hello Bonjo,
Use
comboBox1.Items.AddRange();
or
for each item in itemscollection
comboBox1.Items.Add(item);

Details
I used C#.Net 2005 and SQL 2000 as back end.
I wrote stored procedure to retrieve record (for the report) from the server.
I used Crystal Report (C#.Net 2005) to prepare the report through crystalReportViewer.
I also wrote codes in “Code View” of a Form to load the report.
The report runs perfectly in isolation.
The report also runs very well from the Application prior to deployment.
Problem
The report however, could not be loaded after deployment while other parts of the app run effectively.
It generates an error “Load Report Failed” when attempt to load the report is made.
Although, this is my first deployment with crystal report.
Assumption
I suspect the absence of required file(s) that should be added during deployment in order to aid the loading of a crystal report file, since the report runs in “IDE” before deployment or do you think otherwise?
There is also an insinuation from a friend of the need to add a product key or license key or registration number for the crystal report to work fine, which I do not know the procedure or know-how.
• Please assist in solving my problem so that I can deploy appropriately.
Thanks in advance.

i'm not quite sure what exactly is you problem, is it not being to close the application or not being able to show the forms.
but i did have a look at your code. the code below is in c# (which is similar to your code) and worked fine for me.
form1:
------
<br />
private void btncancel_Click(object sender, System.EventArgs e)<br />
{<br />
if(MessageBox.Show("Do you want to exit","Exiting",MessageBoxButtons.OKCancel,MessageBoxIcon.Question)==DialogResult.OK)<br />
Application.Exit();<br />
}<br />
<br />
private void btnnext_Click(object sender, System.EventArgs e)<br />
{<br />
Form2 objform2=new Form2(this);<br />
objform2.ShowDialog();<br />
}
form2:
------
<br />
private Form1 frmForm1;<br />
public Form2(Form1 objForm)<br />
{<br />
frmForm1=objForm;<br />
}<br />
private void btncancel_Click(object sender, System.EventArgs e)<br />
{<br />
if(MessageBox.Show("Do you want to exit","Exiting", MessageBoxButtons.OKCancel,MessageBoxIcon.Question) ==DialogResult.OK)<br />
Application.Exit();<br />
}<br />
<br />
private void butback_Click(object sender, System.EventArgs e)<br />
{<br />
frmForm1.Visible=true;<br />
this.Close();<br />
}<br />
<br />
private void Form2_Load(object sender, System.EventArgs e)<br />
{<br />
frmForm1.Visible=false;<br />
}<br />

hi!
whenever an click event of any control occurs in my C# asp.net web application(visual studio.net 2003), form load is called again and all controls are initialized. Like i m using check box in my grid and want to capture my check state against any button click. But when i click button then form is again loaded and all check boxex became converted in their default state(which is unchecked).
therefore the following condition in my button click event alwayx bacame false coz at that time no check box is in checked state.
the condition is
if(checkbox.checked)
i have many other problems also due to this from loading against any event. Therefore can u tell me how to stop this loading every time.

Hi,
Are you controlling if the PageLoad is from a postback (IsPostBack porperty)?
|
|
|
|
|
Check whether viewstate is disabled at any level.
Control/Page/Web.Config

Hi,
I have a C# appln, which contains a explorer style Tree view. Whenever any folder or file is created in the Windows Explorer externally, my application Tree view has to update. Is there any windows file system refresh event or message is there to call my method to update Treeview.
I hope you understand what I mean.
Thanks in advance...
Best Regards,
Sunil Jampa.

Hello,
// Create a new FileSystemWatcher and set its properties.
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = args[1];
/* Watch for changes in LastAccess and LastWrite times, and
the renaming of files or directories. */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch text files.
watcher.Filter = "*.txt";
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
// Begin watching.
watcher.EnableRaisingEvents = true

Hi Nishu,
Thanks for the reply!
Actually, whenever any file or folder is created/deleted in any drive irrespective of path in the Windows explorer, my method has to update for that event.
Here Path you mentioned is particular to a specified directory, if i am right. But external changes to the Windows explorer, I dont know which file/folder in which directory, it was changed.
How can I update my Tree view, if any Windows Explorer File System refreshes. I need a standard File System Refresh done by windows explorer.
Thanks again in advance...
Best Regards,
Sunil Jampa.

Hello,
This is the only way I can think of right now ,but I think you should select path as a root path for each drive that will take care of all the events unde.Have you try that.??
