Is there any specific reason why you need the dll in C++? If your C++ dll is on .NET framework, you can directly add reference to your c# project. Alternatively, you can use C++/CLI other than C#. So you can use the C++ classes by just importing the necessary headers.

Hello Friends,
protected void grdEncounter_RowDataBound(object o, GridViewRowEventArgs e)
{
GridViewRow grdEditRow = e.Row;
if (grdEditRow.RowType.Equals(DataControlRowType.Header))
return;
grdEditRow.Cells[2].Text = grdEditRow.Cells[2].Text.Equals("1") ? "Yes" : "No";
}
error comes in above line
Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index
This is the error while loading itself i don't know how to solve.
Regards
JK

seems like your grdEditRow.Cells doesn't have a cell with index = 2
Intelligence is almost useless for those who have nothing else!

I suspect that grdEditRow.Cells[2] doesn't exist for some reason. Try running in debug and have a look exactly where it errors and you should be able to see the cause.

I have to get the price (currency) from a database table, but I can not assign double & Decimal variable to it, which define type I should use?
|
|
|
|
|
If you're using SQL Server use SqlDbType.Money or SqlDbType.SmallMoney.
The need to optimize rises from a bad design.

Unfortunately I had MS Access database instead, but when I used VB.net then I defined Decimal type is OK!
Also I can not re-define the database differently, because other applications are still using them (VC++)
Any new suggestion?
Thank

Could you post the parts of the code that are not working. I don't quite see why decimal wouldn't work.
Also are getting an exception. If so, what is it?

Hi,
I need to create a list box with 4 columns: text, 2 radio buttons & a check box. I am using VS2003. Can somebody let me know how to get about to do this or if there is an alternative way around it.
Any help would be greatly appreciated.

Half-Wit, sorry Life got it right, use a datagridview. You will need to add the radiobuttons manually but the will article on CP to help.

I just cant figure out how to open an existing playlist using the WMPLib.WindowsMediaPlayer object.
I have an existing playlist i want to open, but i have to somehow get it into an IWMPlaylist type first, yet i cant seem to find a method that will do this.
Can anyone help?

I'm not sure, but if it comes to it, it shouldn't be that difficult to read in the file yourself.
WPL files look kinda like this:
<?wpl version="1.0"?>
<smil>
<head>
<meta name="Generator" content="Microsoft Windows Media Player -- 10.0.0.4058"/>
<author/>
<title>Kaiser Chiefs</title>
</head>
<body>
<seq>
<media src="..\..\Kaiser Chiefs - Employment\Kaiser Chiefs - Everyday I Love You Less & Less.mp3"/>
<media src="..\..\Kaiser Chiefs - Employment\Kaiser Chiefs - I Predict A Riot.mp3"/>
<media src="..\..\Kaiser Chiefs - Employment\Kaiser Chiefs - Modern Way.mp3"/>
<media src="..\..\Kaiser Chiefs - Employment\Kaiser Chiefs - Na Na Na Na Naa.mp3"/>
</seq>
</body>
</smil>
So you should just be able to use XmlReader and reconstruct the playlist to a IWMPlaylist

I can read them with an XmlReader no problem, but i cant get a .wpl file to a IWMPlaylist format so i can use the mPlayer.playlistCollection.importPlaylist(IWMPlaylist playlist) method;
I could recreate the whole playlist, by reading the xml and using the media src property to create new IWMPMedia items, then loading each of those into a new playlist, but i cant believe there isnt a simple way to import a playlist...
This is what i am doing at the moment:
<br />
playlist = mPlayer.newPlaylist(plName, openFileDialog.FileName);<br />
<br />
mPlayer.playlistCollection.importPlaylist(playlist);<br />
but this creates a copy of the playlist, so if i open playlist.wpl, i get a new file called playlist(2).wpl, appearing, then if i open it again later, i get playlist(2)(2).wpl.
I could delete the duplicate file every time i open a playlist, but im thinking there has to be a better way...
all i want is a method that lets me create a IWMPlaylist object from a path to a .wpl file.
MSDN has been absolutely no help...

I use Winforms RichTextBox control to edit scripts. Scripts are plain ascii texts.
When error occurs, script engine returns character position of error in code as integer.
How to position cursor to this character position ?
RichTextBox does not have current position property.

Hi Andrus,
I got 2 options:
richTextBox1.SelectionStart = 50;
richTextBox1.SelectionLength = 0;
richTextBox1.Select(60, 0);
The second property/attribute that I´ve set 0 is the length of the selection, if you want to select some text, you can send the length of the selection, but if you don´t want to select, send 0 and then the cursor was positioned in the index.

Set the selection start to the character position you want, and the selection length to 0
richTextBox1.SelectionStart = position;
richTextBox1.SelectionLength = 0;

Hello,
I am using multiple SqlBulkCopy objects within multiple threads to write data into one common database table. The data is obtained via a custom DataReader implemented to read from a common data source.
So now I´m starting 3, 4 or 5 threads almost at the same time to write into the same data table and most times this all works out perfectly. But sometimes a deadlock occurrs on the server and one of the .WriteToServer(Datareader)-calls breaks with an exception. No matter, if I do or don't use 'implicit transactions' option.
So I am wondering how this can happen ? I am referencing the same target table on the server - so in my opinion it may happen that one transaction block the others - but there should never be a deadlock because there is no cyclic dependency of used ressources.
Or am I wrong with my assumptions ?
Does anyone have an idea what happens in this case ? Or did anyone experience the same problem ?
Thanks in advance for any ideas,
Juergen

Reason for this could be lock escalation where you have a conflict when sessions try to escalate the lock to cover the same area.

Hello Friends,
I'm developing an application that reads file properties and stores them in a MS-Access database. I need to know, what would be more efficient in terms of speed, the GetDetailsOf method or the FileInfo and DirectoryInfo classes.
|
|
|
|
|
Test them both and see.
Write the two methods of reading the file properties
Write a loop that repeats the file reading (say 1000) times. You need to do it lots of times because generally just doing it once will be so fast you can't time it accurately.
Use a System.Diagnostics.Stopwatch to time the loop. Repeat for both types of file read.

Like the other reply said, make two versions. But I'd suggest using a profiler to make the comparison, if possible.
