Every one that I've seen, that's any good, requires training for the plate your going to read (because of the different fonts used in each plate), or isn't free or anywhere close to cheap. Some are even proprietary and only exist in the vendors own systems and are not for sale at all.

Please help;
For a couple days I've been battling with writing a report that has to tables linked by a Inner join.
I think I found a work around. I'm using an SQL SERVER database.
Crystal was creating the following query:
SELECT t_EMPINFO.c_EmpFName,
t_EMPINFO.c_EmpCode,
t_Employee_Salary.c_TotalIncome, t_Employee_Salary.c_TotalDeduction,
t_Employee_Salary.c_TotalSalary
FROM t_EMPINFO INNER JOIN
t_Employee_Salary ON t_EMPINFO.c_EmpID = t_Employee_Salary.c_EmpId
WHERE (t_EMPINFO.c_Softdelete = '1') AND (t_Employee_Salary.c_SoftDelete = '1') AND (t_Employee_Salary.c_Year = ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) 'PARAMETER1') AND (t_Employee_Salary.c_Month = 'PARAMETER2')
IN Above Query In place of PARAMETER1 and PARAMETER2 I want to pass Differnt value at the run time (e.g 2007 , 01 ) how it's set dynamically
I have questions though:
1) Is it possible to change the sql that crystal generates without writing my own sql command?
Thanks again for all of your help on this!

I've had similar problems. This is the best I came up with:
1)
create it in your main thread, not in some other thread
2)
Dispose of it in the Dispose method of your main form
protected override void Dispose(bool disposing) {
if(disposing) {
if (components!=null) components.Dispose();
notifyIcon.Dispose();
}
}
3)
If your program crashes, or you abort it using a debugger, the notify icon
remains visible until you hover over it.

hi
i want to use Store Procedure for Insert,Update and Delete data in sql2005 and VC# 2005,but how to do?
please give an example or article or source for me.
thanks

When you create your SqlCommands, set the CommandType to CommandType.StoredProcedure. Also add the parameters needed by the stored procedure. E.g. something like this:
using (SqlConnection mySqlConnection = getConnection())
{
SqlCommand insertCommand = new SqlCommand("[dbo].[MY_INSERT_PROCEDURE]");
insertCommand.CommandType = CommandType.StoredProcedure;
insertCommand.Parameters.Add("@StringField", SqlDbType.VarChar);
insertCommand.Parameters["@StringField"].Value = "Nice new string";
insertCommand.Connection = mySqlConnection;
insertCommand.ExecuteNonQuery();
}

Have you tried searching the articles on this site? I recall an article on "arbitrary links" in a rich text box control.

The following code shows "Column1" as column caption.
Why ?
How to force DataGrid to display "Caption" as column caption ?
using System.Windows.Forms;
using System.Data;
static class Program {
static void Main() {
Application.Run(new Frm());
} }
class Frm : Form {
public Frm() {
DataTable dt = new DataTable();
DataColumn column = new DataColumn();
column.Caption = "Caption";
dt.Columns.Add(column);
DataGrid dg= new DataGrid();
this.Controls.Add(dg);
dg.SetDataBinding(dt, "");
} }

The DataGrid uses the DataColumn's ColumnName as the column caption. The ColumnName defaults to Column1, Column2, etc., so that's why the code shows "Column1" as the caption. If you set the DataColumn's ColumnName to "Caption", then that will be the caption displayed in the DataGrid.

The error should be getting caught, but is getting rethrown in the throw; line.
Are you certain it's not getting caught and rethrown? If not, then it's as if your application isn't running that code.

Did the message box show up?
After the message box is shown you rethrow (throw in C# without an exception object in side a catch block compiles to the MSIL rethrow operation) which takes the exception and continues to unwind the stack with it.
Also, if you need to rollback a transaction, it would be better to do that before having the process wait on user input because then you start locking other people out of parts of the database until the user responds.

Hello friends
Happy new year!
There is a project that is needed to match signature of different person,Is there any component for C# that can do it?(If you recomend a free one,It is better!)
Thanks!
|

Most signature recognition systems work on how the signature is generated. It captures input from a special stylus and records information such as direction, speed and pressure.

Greetings!
I want to create project with video abilities.
Here is short description of my needs:
Application needs to be done with .NET Framework.
Application should consist from two parts:
Client application and server application have different functionality, but they both should work with web-cams installed on their sides (client and server sides).
First part is a client application.
Client application can connect to different web – cams and see content of web – cam.
User of client application can talk to server application using microphone and listens answer from server user.
Except this, client application should have ability to save video from server side.
Server application should have similar video abilities with client application.
I analyzed different technologies for my purpose and I lost one's the head in technologies.
Please suggest me what technology best suites for my project.
Thank you all for your attention for my question
Best Regards,
Alex
