dataadapter.update problem

Hi I am reposting the following message in case anyone can help,
I am creating a generic data access module for an application and I
have come across the following problem:

A form calls the function that loads data from a table to a grid. Then
the code below is called in order to effect any changes in the dataset.
The problem appears with a table that has 43 columns. When in the
selectCommand I pass a select statement containing up to 32 columns it
works without problems. When I increase the number of columns it gives
a "Concurrency violation: the UpdateCommand affected 0 records."
exception. Is this some because of some limitation or am I making an
error in the code?

The table contains 4555 records

public void SaveDataFromGrid(DataSet dsName, string dtName, string
selectCommand)

{

//DGM 20040109
//This code works only for single table updates.

//Create new Connection
OdbcConnection dbConnection = new OdbcConnection(strConnectionString);

//Set the sql command that will fill the dataset
OdbcCommand sqlCommand = new OdbcCommand(selectCommand, dbConnection);
sqlCommand.CommandTimeout = 30;

//Set the sql command that will update the dataset

//Set the data adapter
OdbcDataAdapter dbDataAdapter = new OdbcDataAdapter();
OdbcCommandBuilder cb = new OdbcCommandBuilder(dbDataAdapter);
dbDataAdapter.SelectCommand = sqlCommand;

//Open the connection
dbConnection.Open();

//Fill the dataset with the data
dbDataAdapter.Update(dsName, dtName);

//Close the database connection
dbConnection.Close();
//return true;

}

Thanks in advance for the help

Hi,I have a UserControl that contains a Panel in it.
I add the UserControl to a Form.
I want (at design time) to be able to add, remove, move ,etc, controls on the Panel contained in my UserControl in the same way i would do this if the Panel was placed directly on a Form.Any Ideas?
Thanks!

Hi all,
Does anyone how can I creat a mapfile for my c# project?

For c++ project it's very easy.
You can do it from Project Settings,
just need to set generation of mapfile in Link Tab.
How can I do the same for c#?

Thanks in advance,

Anna.

It has been a while since I've done any C++ and I can't remember what a map file is. Could you remind us? Perhaps it is called something different in C# but the description of what it is and does will help jog the memory.

problem displaying a usercontrol

I have a problem i was hoping someone could help me.

I have a windows form and based on a menu selection i'll display a specific user control uc1 that has various information on it (like a calender with appts on it) when i press down on the mouse I want to present another user control uc2 (this is a custom drawn via gdi+) at a specific location. I set the uc2.Location as to where I want uc2 to appear. This is where my problem occurs. Wherever i press the mouse on uc1 it uc2 always appears at a location just above and left of the mouse based on the location where i press the mouse on uc1. also note when i press the mouse down uc2 initially briefy appears where i want it but than moves/appears just above and left of the mouse. I also dispose of uc2 when the mouseup event fires.

i also use the mousedown event to move uc2. this works fine (but with the location problem) and uc2 moves fine but starts from the location just above and left of the mouse not where i had set the position via uc2.Location.

note i also use uc2.visible=true and uc2.BringToFront()

Does anybody have any ideas?

As always - thanks in advance for your help

Hi all!!!

i'm quite bored with a problem I can't solve.
I'm doing a program which imitates the mouse, and I need that when I do "click" (double click or whatever) in another application, although the latter is actived now, I want my window to still keep the keyboard input to can handle it.

I have try with SetFocus() and GetFocus() from Windows API but I can't make it works.
If you could help me,it would be great;)

Thanks,

ciao!

Thanks Mazdak...

I was just working with hooks now, and I succeded getting all the keyboard input. But then I have a new problem which seems easier but I cannot solve.

In a form with some controls (all of them buttons) how can I know wich button is selected? I'm trying with the focused and containsfocus property but it's not working.

And the last thing... in case I could know which control is selected, how could I generate the click event of this button without actually "click" it?..

Thanks;)

Not sure but you can look through:

GetFocus() or GetGUIThreadInfo() API

BegoBergua wrote:

Look for SendMessage() API. I remember that there are some samples in CP. Use search textbox at the top of the page.

On a textbox? What kind of textbox are we asking about -- WinForms, webforms, html, etc?

Any remotely useful information on my blog will be removed immediately.

Sure. Using System.Runtime.Serialization(.Formatters.Binary):

Example:

            string[] a = new string[3]{"One", "Two", "Three"};<br />
<br />
            BinaryFormatter formatter = new BinaryFormatter();<br />
            MemoryStream stream = new MemoryStream();<br />
            formatter.Serialize(stream, a);<br />
<br />
            stream.Position = 0;<br />
            string[] b = (string[])formatter.Deserialize(stream);

Hope this helps,

As an addendum to turbochimp's example, please reference my response[^] to your post in the ASP.NET forum. In the future, please don't cross-post to multiple forums. At least give people a couple of days to answer the first post before reposting to another forum.

Hope that helps. Smile | :)
