Yes. You simply use ADO .Net classes to handle these operations. You'd need to make a ConnectionString to the Database provider -in your case dBaseIII- using OleDbConnection class, and use SQL commands -eg. CREATE TABLE-. You can call the commands using OleDbCommand class.

With your C# program, load the data from the dBaseIII and then insert into Access...Pretty straight forward.

There is no such built-in functionality if that's what you're asking for. You have to keep track of the files yourself by storing their paths somewhere (application settings, custom XML file, ...) and built the recent files menu dynamically on this basis whenever it pops up.

How to read XML file from end/last using filestream pointer

I have an XML file that contains lot of records.
For performance reasons, i wanted to read the file using filestream and streamreader. Also, it should read from the last. I need to retrive latest records.
How to move to previous line??

Previous line wouldn't work directly. You can seek reversely byte by byte until you read a New Line character. This way you'd know that the last line has ended, and now you are in the previous line.

But this is very tedious. Are you sure you can't just use XPath to get your nodes?

Simulate typing in a texbox control? Newbie Needs Help!

Basement Dweller25-Dec-06 18:25

25-Dec-06 18:25

Hello Freinds,
I am a newbie of about 4 months old, and have been trying to figure out how to simulate typing in a textbox control. I seem to have it all figured out except for the fact that the text appears all at once into the txtbox control rather than one character at a time and at a specified time delay.

What i have done so far:

I have a windows form with a button called (btnType)and a textbox(txtType).
When the button is clicked data is read from a comma deliminated file into the "string[]DeliminatedStrings" and from there the chosen deliminated string is loaded into a Char[] called "charSubstring" which has two parameters, "int Starting index, and Length of substring. The last "while" statement concatinates 1 letter of the substring from the deliminated file at a time, assigning it to the text property of the textbox control called txtType.

The "Tread.Sleep" command is used inside the "while" statement so that the text that is being assigned to the textbox control will be assigned at a delayed interval. I was hoping that at runtime this would simulate a user typing text, one character at a time, however, it appears that i have got something wrong because the text appears all at once into the textbox control.

I have messed with the delay times for the Thread.Sleep method but to no avail. It seems that all the delays happen first than the text is assigned all at once, instead of after each individual character assignment like i was hoping. Any help would be greatly appreciated.

Thanks Code project!

private void btnType_Click(object sender, System.EventArgs e)
{
StreamReader srReadFile = new StreamReader("C:/file.txt");
string readFile = string.Empty;
string[]DeliminatedStrings;
string txt2type;
char[] charSubstring;
int arrayPosition = 0;
int delay = 300;

while ((readFile = srReadFile.ReadLine())!= null)
{
DeliminatedStrings = readFile.Split(',');
txt2type = DeliminatedStrings[1];
charSubstring = txt2type.ToCharArray(0,txt2type.Length);

while(arrayPosition <= txt2type.Length - 1)
{
System.Threading.Thread.Sleep(delay);
txtType.Text = txtType.Text + charSubstring[arrayPosition].ToString();
arrayPosition ++;
}
}
}

The text gets inserted all at once as your btnType_Click event handler runs on the main UI thread and therefor no other messages are processed until it is done. They are queued in the message pump and get executed after the event handler finishes. Take a look at the Control.Refresh method that forces a visual control to redraw itself immediately.
