Hi all, i am experiencing a program lock up issue using entity framework and object datasource..Let me explain the problem..
As usual, from the datasources i choose my entity object and drag some fields to the windows which are a mixture of combobox, some fields are empty and some fields are are filled before. The problem is, when i enter a text to a textbox or choose a value from a combobox, the program just wont let me choose another entity object field on windows or close the program, even BindingNavigator wont work..The only way to proceed and get the program out of stall is to change the row `from` the datagrid..Normally i would want edit all the fields i have on the windows and proceed to the next Record, but the program just stalls at the entity object field i edit on the windows..
Help would be very appreciated, its urgent

Hi Guys,
I've just finished an application that uses MSSQL EXPRESS as its local temp DB. I just wanna ask, for convenience sake, is there a way i can put SQLEXPRESS into the installation such that it installs "silently", with the other app. I mean, without the user having to run the .exe by himself.

You can make your setup program download and install it as a requirement. It would download it from the MS site. No need to actually bundle it.

From the Solution Explorer right-click 'References' and select 'Add Reference'. Search the list for the assembly of interest, select and click OK.

Maintain a custom collection and add the newly searched item in the list every time. Bind the data grid with the collection.

Though your message subject a bit different than what you want to achive ( you are actually not searching grid rather trying to display appened result  it seems ), here is how you can achive that
1. Create an empty DataTable with columns that you want to display in grid.
2. Get the seach result from DB and "append" new result set ( one or more row which comes as your search result)
3. Bind the "updated" DataTable object to grid.
Let me know if you can do that.
Let me know if I have misunderstood your mesasge.
Thanks,

How to access particular method in overloading
E.g: 2 overloaded method as follows
Method1(double, double)
Method1(int, int)
calling method:
Method1(1,1)
Here from calling function i want to access Method1 with "double".
how can we achieve this.
|
|
|
|
|
Cast the variables to the expected type, as follows:
Method1((double)1, (double)1);
|
|
|
|
|
|
Method1(1,1)
This will by default call Method1(int, int).

The OP wanted to call the double version, not the int version.

Hi, How can we know when Don't send Dialog occur in c#?
|
|
|
|
|
This is nowhere related to C#.
If any application experience an error that it is not prepared to handle, OS stops the application and prompts you the error dialog.

Hi everyone,
I have a Windows application developed in C#. I use MS-Access database and OLEDB to connect with the database.
One of my client faced problem while executing the software. While studying the error log file that the software created, it has:
No error message available, result code: E_UNEXPECTED(0x8000FFFF)
The same client is able to run the software on other machines in same network. I have no access to the cilent machine. If anyone has experienced such situation or have any knowledge about how to resolve this then it will be of great help.
I have asked the client to provide the Windows Event Log.. that might be helpful.
Regards,
-SIFAR.

Seems to be a permissions issue, can you check that the client have sufficient permissions to access the DB?
Regards,
Prakash Kalakoti

Thanks Prakash,
I agree with you that permission might be the issue. But the database is created with the installation process of the software. And the client faces the problem from very first exectuion. (And i think that the client does not have MS-Access installed on his machine)
I will work around this and post the result accordingly..
Regards,
-SIFAR.
