Hi I am trying to hide some rows in a DataGridView , in some rows an unhandled exception is fired with the following message . (( Row associated with the currency manager's position cannot be made invisible.)) handling this exception will cause the row to remain visible . Any Ideas ?

Yes , but does not save the value of that cell !!! I don't know why !!! the only way to save it is to click a different ROW within the grid .

the problem is even if you save by clicking a SAVE button which will fire AcceptCanges() method , the contents of the cell are not saved unless the user previously leaves the row which include that cell .

Hi When changing a value in any cell in DataGridView , this value is saved into the related dataset only after the user clicks on an other cell in an other row ! Even the mecthod AcceptChanges() will not save the contents of this cell unless the user moves to an other row . I need to save these contents straight away without forcing the user to leave the cell . any Ideas ? thanx .

Hi I am building a windows Form application where the Forms names are stored in a data table as text , The name of the Form selected to run is retrieved from the data table , so it will be a string type , how can I call the related form knowing its name as a string only ? Any Ideas ?

Actually , if the first data cell in the column is numeric , the full column is read as numeric and any text in the same column is read as blank . and if the first data cell is text then the full column is read as text and any numeric cell in the same column is read as blank . I have columns with mixed data , some numeric only and some are string . any hints ?

I am trying to read an Excel sheet to my program using OleDbDataAdapter into datatable , this is working fine except that if the excel column is text and taken into string field in the datatable its read as blank . anyone came across such a case . I am using ,NET 2.o framework with visual studio 2005 - C# . thankx

Hi I have a small problem here which I am trying to solve . I have many Windows Forms in my application which I want to call and show each one based on its name , the name is stored in a database table as a string variable , this table is changeable by the user . I repeat the only thing I know about the Form is its name as a string variable . assume no parameters are to be passed to the Form > any Ideas Thanks We will Either find a way , or make one .

Yes I know that you have to put it on the desktop as a shortcut from the server and run it locally on each user machine , but the application does not run that way , an exception is thrown , also the more users run the application at the same time the slower it gets . Oracle has a concept of "Application server " like a web server but used for forms based application .

I have an application written in C# , and I want the users to run it from the server ( windows 2003 ) without having that application installed on each and every machine using it , Just from the server . So the user has to log to the server only to be able to run it this application . is that possible , any Ideas how to do it ? Regards Dean

Thanks Luc Yes , sure you can change the tooltiptext of the tree , but there is no event to be triggered returning the node name or path when hovering over the tree . Nodes are not treated as objects in the tree , there is no Mousehover event for each node . I did try to find articles on the same subject in codeproject , but could not find any , if you know any of these articles please tell me . Thanks UnitecSoft We Will Either Find A Way Or Make One .

Hi everyone I need to add a tooltiptext in that yellow rectangle for each node in a treeview in C# . is that possible , anyone has an Idea ? Thanx UnitecSoft We Will Either Find A Way Or Make One .

hi everyone Just to share the information , The reson of being unable to connect to sql server database via C# application was due to the anti virus protection I am useing ( Kaspersky ) . Disabling this program will solve the problem . maybe there is a certain setting within Kaspersky to allow or deny this access . :-D UnitecSoft We will Either Find A Way Or Make One .

I Don't think its a user privilege problem , no reason to have a successful connection in the first run then a failure connection in the second run while no changes in anything between the two runs . could it be a setup parameters problem for the .NET framework or SQL server . I will try to change windows Authentication to sqlserver security . UnitecSoft We will Either Find A Way Or Make One .
