Re: Simple way to play audio/video file in form? - C# Discussion Boards

11-Jan-07 12:01

Is there one (and possibly if that include media player call, hide it's actually MP, but I hope to more elegant solution anyway)?

I know I seen some presentation where they did quick example of it, but can't remember how...

So?

Can you explain a bit more clearly what you're trying to achieve.

Enable user to play audio or video of their choice... is there some namespace that deal with this?

No. You need to use the windows media player control, or involve the DirectShow platform, which requires the PSDK.

Are you an Iron Maiden/Black Sabbath fan, or does your name mean something else ?

Definitely big fan of Iron Maiden, but also like Ozzy Osbourne as well so I combined name of two songs into nick name... Big Grin | :-D

Direct X SDK or?

Anyway first one looks to be more simple... how to do it some simple example please if possible?

I saw Maiden in Toronto - awesome.

DirectShow is in the platform SDK. Intuitive, no ?

The WMP control is actually more code, but you have it already. Just google, there are plenty of samples out there for both. The DirectShow comes with samples, too, but it's pretty self explanatory.

[ot]Never seen Maiden live, last time they were here I was 7... so that was long time ago actually, now they promise each year they will come but always miss our country for some reason (mostly local promoter don't have enough money to pay in advance, event though I'm sure it would be great concert, every 2nd kid in town during summer have IM T-shirt, so go figure)...[/ot]

Thing I seen on local MS presentation was, guy dragged button on form, and written simple event that opened and played media (audio) file from disc on click... but I guess it was just System.Media.SoundPlayer call (and at least to documentation it only play wav)... so not much use of that...

anyway I'll go for second solution I guess... I'll return later if I can't figure out how to do it... Poke tongue | ;-P

BTW visit this www.ironmaiden.co.sr not in English... but anyway...

You need to right click on the toolbox and choose 'change items' or something, and you get a list, from there you can add WMP to the toolbox. Then, you can indeed drag it onto a form.

I believe the control has a Url property, it has something like that, which you can point to a file, and it will just play it. It has a property call CtlControls, or something, under that are methods like play, pause, stop.

This work, I guess that is best solution, what is minimal version of MP that user should have in order this to run?

Does it work on 2000/ME/98?

does 2.0 run at all on 9x systems? how about 3.0?

Christian Graus12-Jan-07 9:27

12-Jan-07 9:27

.NET 2.0 requires 2000, and 3.0 requires XP.

In .NET 2 I think there's a SoundPlayer [^]component that you can drop onto a form.

I have no idea what I just said. But my intentions were sincere.

How do I trap the event that is fired when the column header of a Datagrid is clicked?

This is from MS Help file example.
It might be usable to your occasion.
//===================================
private void sortButton_Click(object sender, System.EventArgs e)
{
// Check which column is selected, otherwise set NewColumn to null.
DataGridViewColumn newColumn =
dataGridView1.Columns.GetColumnCount(
DataGridViewElementStates.Selected) == 1 ?
dataGridView1.SelectedColumns[0] : null;

DataGridViewColumn oldColumn = dataGridView1.SortedColumn;
ListSortDirection direction;

// If oldColumn is null, then the DataGridView is not currently sorted.
if (oldColumn != null)
{
// Sort the same column again, reversing the SortOrder.
if (oldColumn == newColumn &&
dataGridView1.SortOrder == SortOrder.Ascending)
{
direction = ListSortDirection.Descending;
}
else
{
// Sort a new column and remove the old SortGlyph.
direction = ListSortDirection.Ascending;
oldColumn.HeaderCell.SortGlyphDirection = SortOrder.None;
}
}
else
{
direction = ListSortDirection.Ascending;
}

// If no column has been selected, display an error dialog box.
if (newColumn == null)
{
MessageBox.Show("Select a single column and try again.",
"Error: Invalid Selection", MessageBoxButtons.OK,
MessageBoxIcon.Error);
}
else
{
dataGridView1.Sort(newColumn, direction);
newColumn.HeaderCell.SortGlyphDirection =
direction == ListSortDirection.Ascending ?
SortOrder.Ascending : SortOrder.Descending;
}
}

Thanks Jamestown48,

I saw this too but it's not quite what I wanted. When a user clicks on the header of a column, I expect that an event is fired and datagrid processes it by sorting the rows accordingly. What I have in mind is that after this event is fired and datagrid does what it has to do, I will do my own processing (i.e. add an extra row to the bottom of the newly sorted rows).

I dunno if my question is too simplistic but I just couldn't find any resource for it.

Language Translation in .Net Web application

I want to translate data from one language to other in one of my .Net Web application. Say for instance from English to Chinese and vice versa. Any idea on how to do this. Are there any free source translation libraries available.

Thanks

There is no translation library. There is multi-language support but people have to author all the data in all the different languages. The multi-language support provides mechanisms for the application to use different assemblies containing the string tables (authored by people) in different languages based on the users PC language settings.

Header files included in Web Services?

joeller11-Jan-07 10:34

11-Jan-07 10:34

I have a question that I am sure has been answered many times but I have been unable to find any references on the internet and my attempts to program the situation keep failing and I am running out of time.

In designing ASP.Net Web Applications with c# and VB.net I have been able to deploy these applications with only the contents of the bin directory. When I have included third party or in-house class library in the Web app I only needed to include the assembly file (dll) of the class library I am referencing.

Now I am trying to analyze alternative designs for a Web service which references a C++ DLL. We want to redesign the DLL as a Visual C++ 2005 DLL, and to reference that assembly in the Web service project. One of the alternatives is to create a visual C++ 2005 ASP.Net web service that references the DLL. I want to report in my evaluation of this alternative that creating a refereence to this Managed assembly of the class library eliminates the need for including the header files in your Web service project. I also want to say that deployment would only require copying the Web service's assembly and the class library's assembly into the bin. (In addtion to the disco, the web config, the asmx, the asax, etc.) But it occured to me I had never actually tested that. Nor had I seen anything written on that. So I tested it first for a c# web service which of course verified my second point. However, when I tested a C++ Web Service I was either unable to successfully compile the Web service, (Error kept reporting the DLL had no copy constructor (which it didn't) when attempting to instantiate object using gcnew:
TestDLL::clsPerson^ Me = gcnew TestDLL::clsPerson;

or else it would compile successfully but error in the invoke method of the debug when I declared it with out instantiating it.

TestDLL::clsPerson^ Me;

(note I did not use it at all in the return from the Web service.)

At this time I really do not care why it failed I just want an answer to my question.

Is it necessary to include the header files from a Managed class library in the Web service when the assembly is referenced using VS 2005 "add reference"?

Please help me as this is VERY time sensitive. I need to have this information by Friday 1/12/2007 3:00 PM EST. After that I will have failed in my mandate and it will be of no importance to me as I will be looking for work. Thanks in advance.

Is it possible to use Visual C# to design a form identical or extremely similar to the Visual C# start page? You know how the start page is laid out graphically, is it possible to design a form like that using what ships with Visual C#. I am new to Visual C# and I am trying to get a grasp of its abilities. I am also trying to decide about whether or not to upgrade to Visual C# 2005 Professional from my Express Edition.

Thanks,

It is possible, all you have got to do is use the controls which are shipped with C# and probably you may have to import images and templates
