Hallo, all...
Would you mind explaining me how to create System.Drawing.Bitmap object in C# from image wich was drown by ActiveX object on the form? Is it real to do or not? For example:
SomeAXObject obj = new SomeAXObject();
Bitmap bmp = new Bitmap( ??? );

I just downloaded Anakrino 9 but it keeps crashing. Does it have this issue with .NET 1.1 ? If so, are there any workarounds to this problem?
ILDASM  Come on be hardcore. On a serious note, Anakrino has not implemented all the op codes hence the crashing. I think S.Rod. had a look at the source, but it was incomplete, I guess we shall never get a new version...

The author says on his site that he hasnt had problems with 1.1, but apparently a lot of people have encountered this crash

Their demo version is almost unusable  It allows you to upload .NET exes or dlls to their web site and you get the decompiled output on your browser (that too, with restrictions)

The first comment on the site:
Small Point about .NET 1.1
(as of January 21st, 6:15AM CST)
Note that, as far as I'm concerned, Anakrino Interim #9 supports .NET 1.1. For those of you who claim it doesn't, I only somewhat believe you  . I _accept_ that it might be crashing for you, but I don't think .NET 1.1 is to blame. (I have .NET 1.1, and it works fine for me.) God, I want a better web page...

Ok. I get JUST the basics of c# n ado.net... Aw need some hep...
I gotta dumb little checkbook table, a datagrid and a dataset.
I get the connection, dataset and adapter Fill/Update stuff.
But I wanna:
1) hide the ugly key column
2) be able to update ideally without the dang uniqueidentifier column.
(don't need to insert or delete)
So far I've used the dang adapter wizard.
I hate the clutter it makes tho.
What all do I need to build my own SqlDataAdapter thingy?
Do I have to use a SqlCommandBuilder thingy?
And how do I hide the stupid uniqueidentifier column or lose it altogether?
Thanks for any help ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Make the column .Visible=false?

I make all my DataAdapters in-line now. Think along these lines...
using (SqlDataAdapter sqlDa = new SqlDataAdapter("SELECT foo FROM MyTable", sqlConn))
{
sqlDa.Fill(myDataSet.myTable);
using (SqlCommandBuilder sqlCb = new SqlCommandBuilder(sqlDa))
sqlDa.Update(myDataSet.myTable);
}Steve Hazel wrote:

Not if you want to build the update commands manually, but as you can see above, it's not that complicated.
The CommandBuilder sets itself up as a listener for .Update commands on the given DataAdapter. Then (as its name suggests) it builds the essential commands for the updates you want to do.

Hi,
I would like to do something like ICQ, where by, whenever a message is received, the window will flash to get the user's attention whether it is focused or not...
Does anybody have any idea how to do this?

Hi, all,
I am very close to finish my first .NET application( C#, Winform Datagrid, and MS Access database). I can modify all the data in my DataSet on my winform datagrid. NowI am trying for the first time to save the data back to my Access DB. When I call daMyDataAdaptor.Update( for a single table), I got this attached error. It says the UPDATE statement has syntax error, but the Statement was created by the wizard when I configured DataAdaptor, how can it be wrong? I know this must be something I missed, Please help.
Due to size limitation of the attachment, I can not attach the small test program. If you can help me, I can sent you the zip test program.
Code on Save button as follows:
------------------------------------
if ( connMain.State != ConnectionState.Open )
{
connMain.Open();
}
System.Data.OleDb.OleDbTransaction trans = connMain.BeginTransaction();
daTaskList.UpdateCommand.Transaction = trans;
try
{
daTaskList.Update(dsMain1, "LMTaskList");
//System.Exception MyErr = new System.Exception("Error Occurred");
//throw(MyErr);
trans.Commit();
}
catch(System.Exception err)
{
trans.Rollback();
MessageBox.Show("Failed to save Available Tasks!\n" + "Details: " + err.ToString() );
}
finally
{
connMain.Close();
}
-----------------------------------------------------
I wonder what is wrong with the code I have.
Thanks again.

While developing an Explorer Bar in C#, using the BandObject control, the Backspace seems to be ignored -- it is never passed on to the textbox which is a child of my Explorer Bar. A KeyPress event is never triggered for the Backspace key.
What is a good solution? I've heard that trapping the key in TranslateAcceleratorIO is the way to go, which makes sense, but I don't know what to do from there. I wouldn't mind firing an event from there, but how do I fire the event with the right event source? Or is there something I can override to prevent the Backspace key from being trapped?
Thanks,
Arun

Hi All,
I'm not sure what I did you my project, but don't seem to be able to break anymore so that I can step into the code. Everytime I set a breakpoint and run the code the breakpoint shows a little '?' on it and if I mouse over it I get this "The breakpoint will not currently be hit. No symbols have been loaded for this document." It happens no matter where I put the breakpoint. I checked the help, msdn, and google, but couldn't find any information on it. As a note, the problem seemed to start when I added a handler for a keypress event for a textbox. I removed the handler but the problem is still there.
Any ideas? Help is much appreciated.

I think your running the program in Release mode. Switch it back to Debug mode and it should hit the breakpoints.

Yep, that was it. I figured it out about five minutes after I posted and then forgot to post again. Thanks for the help though, it is always appreciated.

You have probably disabled debugging in the project options

Hi,
I am developing a simple WinForm app with datagrid on the form. I want to know when any cell text changed so that I can enable my Save button. What event should I handle? Any example will be even better. Thanks.

Hi,
I'm developing an Explorer bar (using the BandObject control), and I'm moving towards putting all my controls in a form which is inside the BandObject control. Thus, the form's TopLevel property is set to false. I suspect this property setting disables the MainMenu in the form. Is this the case? Is there any way for me to have a non-top-level form that is in a control have its menu display?
Thanks,
Arun

Well, I've done some reading in MSDN newsgroups which suggests the above is not possible. I suppose I'll have to settle with toolbars for now (and rebars later!).
Please correct me if I'm wrong!

Ok, this is abit based on the previous tread I made 'Making of a "Standalone" application'. Whats the point of this? Its like java damnit! I think one have to do C++ or VB then to make standalone apps instead, or? Kinda too bad since starting up a C# project shows up this nice basic window, and your're ready to start doing your application (or in this case, complication) :P Quite much easier to do some thing like this with the already advanced Windows programing. Point/drag and klick. (With more advanced features you have to type code yourself, which is nice)
Oh, and also, C# seems much easier to learn than C++
Someeone care to elaborate this further and explain this to me?

I am with you man!
I especially hate that I have to have Windows to run Microsoft Office. Damnit, why can't I just run Office without installing that Windows crap.
Ugh!
I really recommend you go and read up on the how, why and what of the .NET Framework. Not C#, not VB.NET, not COBOL.NET. Read up on the actual .NET Framework itself. Once you have done that then you can make more informed decisions on what to code your new applications in.
There are some good articles right here on CP about it.

With VB you still have to deliver the VB runtime dlls. I'm afraid your only choices are C or C++. Unless you want to learn Delphi.

C++ also has its runtimes, they just normally included with the OS, soon all MS OS'es will include .NET as standard.

Hey,
I've just started to learn C# here and I must say its quite fun. However, how can I make the applications I make in C# "standalone"? (work without having to install .net) I ask since, well, it would be damn fun if I could make some nice app and show off at friends or something Also, itnt this how ppl do their applications for Windwos in general?? Or maybe its in C++? Maybe its better to develope in C++ if its not possible in C#
Ideas?
Thanks,
Ace
