Hello!
I am using a listview in C# with several columns and rows. Incoming data is added to the top row of the listview while the bottom rows are deleted on regular intervalls.
When scrolling down this list, for checking, for example the last index, the list automatically is scrolled back up to the first row on every new incoming data update. This is very annoying cause I do not want any automatic scrolling.
Does anyone know how to avoid this?

Hi,
//try this
listView1.Scrollable = false;
Thanks.

But I want it to be possible for the user to scroll throught the list, I just don't want the list to automatically be scrolled back to the top.

Well okay just block scrolling when you are updating the list view and then re enable it.
i hope this can solve it the you want it.

Your question is too vague.
What type of graph? line graph, bar chart, pie chart, scatter plot, etc.
What do you mean by a "number of data"? What format is the data in? How does it relate to the graph? Does it supply information for an X & Y axis?

Try looking at the SqlBulkCopy class in the System.Data.SqlClient namespace. I've never used it, but should give you the ability to BCP a file into a Sql table. Or if you google SqlBulkCopy .Net it should return you some sites to check out.

I've created a C# application with an Access DB on the back end. The problem I'm having is it seems like the code is executing faster than the DB can accept changes. I've got an "Add New" form that the user enters data in to add a new dealer. When the user hits the Save button, I insert the new row and close the "Add New Dealer" form. I then reload my Dealer combo box on the main form from the Dealer table. However, the code seems to be reloading the the combo before the new row makes it into the table. My first thought is to Save the row, then pause the code execution for a second or two to allow the table to catch up. Then continue the code execution and reload my combo. If there's a better solution to the problem (other than getting rid of the Access DB), I'm all ears. But at the very least, I'm looking for help on how to pause the execution of the code in for a specifict interval ("Pause(2)" function below) between the "Insert row" function and the "Reload combo" function. The pseudocode is below. Thanks in advance for any help.
//On main form
private void AddNew()
{
frmAddNew.ShowDialog();//show AddNew dialog
Pause(2);//Pause code for 2 seconds
ReloadCombo();//reload Dealer combo including newly added dealer
}
//On AddNew dialog box
private void Save()
{
CollectData();//Collect user entered data from Dialog
InsertRow();//insert new row into Dealer table
this.close;//close add new form and return control to main form
}

Are you using separate connections for update and reading? Are you keeping the connection open during the execution of the program?
If you keep a connection open for reading and do the update using another connection, there can be quite some time before the change is visible. If you use the same connection or close the connections when they are not used, the change should show up immediately.

That was the problem. I was using two separate connections and not closing them when I was done. I added the close statement and everything is working great now. I thought the Access DB was just so slow it couldn't keep up with the code execution. I've never used an Access DB before, I'm used to SQL Server so I wasn't sure how capable it was. I will slap my wrist for this one, I should know to do better object cleanup. Thanks for the help.

Is your database updated when Save method executes?
If you could send the code which actually deals with data, we could help you much easier...

Make sure you are refreshing the local dataset and not just sending updates to the database. Clear and refill the dataset before ReloadCombo() if you arent already, and you have made sure the local dataset is up to date. I seriously doubt your program is going faster than your database. The program should not continue execution from InsertRow() until the data has been completely updated in the database.

Thanks for the info. I thought it would be odd that the code would execute faster than the DB also, but when I would step through in debug everything work fine. It was just when I executed without breaking that the problem occurred. I am refreshing the local dataset each time. In the ReloadCombo() function the first thing I do is clear the table in the dataset then do a select from the table again. I took the advice from the ealier post and closed my connection after the insert row step and that seemed to fix the issue.
Thanks,
Jake

Hi folks,
I am trying to use C# to get the IIS application pool identity.
I know it's possible to use Vbscript but it seems like there are no equivalent functions, properties in C#.
Do you guys know how?
Thanks,

Could you show me how to display 'a group per a page'
I have some groups and I want to display group1 on page1, group2 on page2.... Could it be possible?
Thanks so much.

You have different sections for each group. If you dont have more data than can fit on a page, then it is possible. Otherwise the group may go to another page. You can make the next group display on a new page by selecting the "new page after" property in the section properties.
