Hello

1- Call CreateFile() and supply it with the name of the port
2- make a FileStream object and give the constructor the handle returned from the above call
3- Use the stream to read/write data from the port.

Regards

You could just start the command line compiler of java (System.Diagnostics.Process.Start(...) and check if the appropriate .class file has been generated in the file system.

Hi,

Just execute the command from your c# programme to compile the java code and check the output of that,from that determine the success of that,you also dont need to check for the .class file for the perticular .java ,either way you can do that.

Cool | :cool:

1.TO make a ref of progressBar
2.to make a variable global that is accessible in both window application and class library
3.During a thread that is in class library and start at ButtonClick event
how can we check the variable of thread at control event during the thread execution.

Probably by defining it in the class library, then the windows app can access it. You can't have a global, a public static on a class is the best you can do.

So, you are looking for a class library that can make a progress bar display processing progress to a WinForm assembly. Am I right?

Create table

Hi I need to create new tables from my program in a Access database. I'm using the odbc components and sql queries to access the database.
What would the query look like?

Thanks

Guffa28-Sep-06 1:16

Something like:

"create table Users (Id int primary key, Name varchar(100))"

Look up the reference for the create table command for complete syntax.

I would recommend using OleDb instead of OCDB, if possible.

Also, creating tables is something that you would not normally do from code. If you feel that you need to add tables dynamically to add more data, most likely your database design is not flexible enough.

I am unsure if you can just pass create table syntax to Access, or if you need to use ADOX.

You want a class library, which is consumed by an app, to access variables in the app ? The best you can do is define delegates which can call back into the main app if they want to change the variable, and keep a local variable which your windows app can set.

Actually, if it's a class, passing it through from the windows app should maintain a reference, which means changes will be reflected in the windows app.

It depends, what exactly are you trying to do ?

sort an ArrayList of arrays

Hello,

I am using frequently ArrayList's that hold an array of strings. I never had to sort them till now. Does someone point me in a direction to sort them in an effective way?

An example of what I am using.

ArrayList alTemp = new ArrayList();
alTemp.Add(new string[] {string1, string2})

I like to sort them on the first element of the string[].

Thanks!

Have a look at the Array.Sort method, e.g., see the example here:

I checked that before, and it will come up with the following errors:

Error 1 The best overloaded method match for 'System.Array.Sort(System.Array)' has some invalid arguments

Error 2 Argument '1': cannot convert from 'System.Collections.ArrayList' to 'System.Array'

DataGridView with validation events, how to delete row with errors ?

bouha28-Sep-06 0:11

28-Sep-06 0:11

hi all !
it's my first post here so let me welcome myself Smile | :)

ok let me explain my problem : i hawe a windows form in which i have a bound DGV (datagridview) and a bindingnavigator associated to sql server database.
in that DGV i'm using some handler events CellValidating, RowValidating... and DGV_DataError so the problem i'm facing is whenever there's a mistaken row in the datagridview i can't remove it with the bindingnavigator Delete button. indeed when i click on the delete button, the row in question, losts the focus and proceed on the validation process and it results in the final to the DataError event, in which i assign e.Cancel = True and that's logic because the entry in the row can't be reflected to the dataset in this case. so the process terminates with the dataError event without processing in removing the row, even when i handle the clik event of the bindingnavigator's Delete button nothing happens it doesn't process.
can anyone help me please Frown | :(

Mouse wheel scroll events ?

My mouse ( and probably yours ) scrolls when you move the wheel left and right. Does anyone know how to capture this event on a window that doesn't have a scrollbar ?

Hello

For what I know WM_MOUSEWHEEL is sent to any window, whether having a scrollbar or not. Use Spy++ to monitor the window you want to catch the event in, then see if the message is sent to it or not. If so, you can easily filter it out.
