Hi,
I'm aware there are some GUI parts that aren't Controls, and hence don't have InvokeRequired and Invoke().
Although I did search a lot at some time, I haven't found any official stance.
I think it is OK to use a real Control instead of the non-Control part for calling InvokeRequired and Invoke(), provided those parts really got created by the same thread the Controls are. In the end, you probably could use the Form itself for all of them. After all, all the object is used for is determining the right thread for executing the delegate.
I haven't checked this yet, it is on my TODO list though.

I am wanting to (in real time) play a mp3 or wav file (can be played from an external source (windows media player plug-in) and interpret the data so that I can do various tasks if it detects certain pitches, frequencies etc...
I have seen many sound API like lame and audiere, these seem to just allow me to load in the songs and call play on them, this is not useful, because I actually need to see the stream data of the song
I have also looked into RIFF parsers, this seems to be more along the lines of what I want, but I guess I would like some more direction as to if there is a better API out there for what I am looking for
So to recap:
Language doesn't really matter I can do C, C++, C#, java, DirectX
I am using a windows machine, also can boot linux
I want to be able to look at the audio data of a file ( format doesn't matter can be .mp3, WAV, AIFF w/e I can convert the music files into whatever) and determine when a certain triggers (frequency, amp etc) take place in a song and have my application react accordingly

I would like to start a second form relative to the first form.
frmMain is the first form,
frmView2 is the second form being opened by frmMain:
frmView2 FView2 = new frmView2();
FView2.Show();
In frmView2 I have:
this.Location = windowpoint;
How do I properly pass a Point from frmMain to frmView2?
Thank you

You have to set the starting location ( there's a property, and I forget it, sorry ), before you show it. You can set it to center screen, center parent, or you can set it to manual, and then setting the position will work.

I have the starting position. The starting point is the point I'm trying to pass from the first form. How do I pass that point per my OP?
|
|
|
|
|
this.StartPosition = FormStartPosition.CenterScreen;
|
|
|

Hi,
1. you need to set Form.StartPosition to Manual
2. you could pass a Point through a second Form constructor, through a new property, and many other ways. However, you don't have to, you could also set the position in the main form, just before showing the new one.

I set the point with this.Location in the first form and set the adjusted point just before frmView2.Show
thanks!!

Greatings, How I can change the color text in datagridview cells?
The Visual Studio 6.0 FlexGrid has an property ForeColor.
Thanks
|

Are you using the Microsoft Flexgrid 6.0 control with C#?
In Visual Basic 6 you'd first have to set the row and column, and then simply change the color. Something like this;
With MSFlexGrid1
.TextMatrix(0, 0) = "black"
.TextMatrix(0, 1) = "red"
.Row = 0
.Col = 1
.CellForeColor = vbRed
End With A DataGridView would give you more options to play with, though

Sorry I tried with MSFlexGrid 6.0, it is a great control, it would must exit too in Visual Studio 2003, 2005 and 2008. But I have 2 problems.
- The scrollbars not work with scroll mouse
- I have Windows Seven Ultimate and i can't install Visual Studio 6.0 is not compatible. An Visual Studio 2003, 2005 or 2008 project developer with MSFlexGrid 6.0 can find the dll file or OCX file in System 32, because the Operative System had or have Visual Studio 6.0. But I can't set to Visual Studio 2005 the path of the MSFlexGrid dll.
I don't Know if Visual Basic 2005 has MSFlexGrid, I only works with C#, but VB 2005 has an MSFlexGrid i can use on C#.
Thanks.

Because the FlexGrid was written before mouses came with a scrollwheel. You'd have to add that yourself[^].

That's a good thing, actually. Why not download Visual Basic.NET Express?

But what is the difference with Visual Basic 2005, I have Visual Studio 2005 full version, all languajes, the controls are common. And FlexGrid is only in the version 6.0.
The most important for me is use the Flexgrid 6.0 with Visual Studio 2005 on Windows 7, but not to install Visual Studio 6.0 or Visual Basic 6.0.
Thanks for the link, I go to see about the scroll.

The only solution is build Visual Studio 2005 projects with the Visual Studio 6.0 components like MSFlexGrid 6.0, is on Windows XP Mode Virtual Machine of Windows 7, but the problem is this applications not run on Windows 7.
I can use Datagridview of Visual Studio 2005, but this component is very slow when load information, wich is not from a Database.
Please, have somebody a solution?
Thanks.

Thanks for your reply
But still my problem is not solve when i use ExecuteNonnquery() method in this style
int result = sqlcommand.ExecuteNonQuery()
MessageBox.Show(result.ToString());
actually message box returns the message that all rows are updated but when i check Position column only one row of column Position is updated and other rows are show old values.
I want to update multiple rows of a single column Position with different positions of students
kindly sent immediate reply i am trying to solve this problem from last 10 days but no progress.
Thanks Usman Ahmad

To update multiple rows, you need to use the UPDATE command.
UPDATE [Table]
SET [Column] = [Value]
WHERE [Condition]

Thanks for your reply
But i am already using this syntax.Still my problem is how to update multiple rows of a single column with different values at runtime from C# using update query

Dear Sirs,
What are people using now for their 3D rendering in C#? I see that the last managed DirectX is a little old now, and it looks like the managade libraries for OpenGL are a little old, too. Is there one of the above that's good and new that I've missed? I am using XNA, but it's very limited. For instance, I would like to render two panels in a form, and I don't see a way to do that...I just looked it up, and see a way to do that, so I'll rephrase: So, is everyone using XNA now? It seems very easy to use, and meets most needs. I'm creating medical imaging programs and would like to have lots of control over coordinate systems, and drawing many panels at the same time on the screen.
Let me know what you think! Thanks.

XNA is not limited. What exactly are you trying to do?

Dear Mr. Aptroot,
Well, I'm just trying to poll users as to their preferences and current usages. I've really gotten my 3D rendering under control. I'm showing a structure set for radiation treatment, and showing where the beam intersects the patient given a certain radius and sample rate. I got that done, but I guess I'll be making more programs sort of like this one, and I was wondering if I should investigate other options. In my original post, which was surely pretty confusing, I admitted that it wasn't limited (after looking something up that I thought was a limitation). So, I guess you use XNA?
In Christ,

Yes, but I've also used Managed DirectX (which is pretty much the same as XNA without the fancy extra's) and OpenGL and native DirectX
What do you really want to do though? (I don't know much about the medical stuff)

Dear Mr. Aptroot,
I must be particularly unclear today. I have the rendering under control, that is, I am done doing what I wanted to do, and now I don't have anything in particular that I want to do. What I WANTED to do was show a body on the screen and allow the user to investigate various structures in the body (the skin, internal organs, tumors, etc.), but I did it in XNA.
The reason I'm polling for other users' preferences is because I am sure I'll be doing more and I'm wondering if anything might be better. Thanks for your persistent help!
When you say Managed DirectX are you talking about that one like DirectX 9? Or are you referring to SlimDX? When you say OpenGL, are you accessing it through the .net, or native? Thanks again.
In Christ,
Aaron Laws
