Hi
Is there as easy way to display row numbers in a DataGridView Control (i.e. in the Row Header cells on the side of the control) which has a DataTable as it's datasource. Also, if a row is deleted, it should re-number the rows
Tks

May i know wat is the syntax to use to get the current date and current time. Sometime like that:
Date = CurrentDate
time = CurrentTime
it is urgent pls help...
|
|
|
|
|
Use DateTime.Today for just the date, and DateTime.Now for the date and time.
See here for more information.
|
|
|
|
|
And if i just wan the time only? btw wat should i add so tt the format of the date is 20-11-2006 and the time is 17:36?
|
|
|
|
|
For just the time, use DateTime.Now.ToShortTimeString.
And for the date, use DateTime.Now.ToShortDateString.
|
|
|
|
|
date = now or now.date
date = now.timeofday
nothing is impossible.....

I'm trying to read a wav file apply a filter to it and save that as a new wav file. I've had no problems doing that but when I try to play the new wav file in Windows Media Player (or any other player for that matter) I keep getting this error: C00D1199: Cannot play the file.
I took a look at the the headers for the original file and the new file and they are completely identical so that doesn't seem to be the problem. Also when I look at the files in the "mycomputer" file manager they have the same size (as they should be). Does anybody have any ideas on what could be the problem?
I will post the header file data below just incase that would be of any help.
,82,73,70,70
,210,19,1,0
,87,65,86,69
,102,109,116,32
,18,0,0,0
,1,0,1,0
,68,172,0,0
,136,88,1,0
,2,0,16,0
,0,0,102,97
,99,116,4,0
thanks,
Mike

You cannot just save a file as a .wav file. You have to convert it.
Have you tried playing your new Wave file in a different media player?
|
|
|
|
|
Yes I tried playing it in another player and got an error with that too.
What do you mean by converting it? I included the header information for it.
thanks you for your help.

You cannot just save files, you must convert them. I'm not sure if this will help, but try looking here.

In that case, your file is obviously corrupt.

If you treat that data as the header, and the rest as data, you have clearly corrupted the file.
That is the header (12 bytes), the "fmt " chunk (26 bytes) and half of the "fact" chunk (6 of 12 bytes).

b { font-weight: normal; }

Yes my header is 44 bytes long and includes all that information you meantioned. And the original file that I am filtering had the exact same header and was produced by another program and has no problems.
ps the commas are not actually in the header I just added them automatically when I read the data from the wav file.
thanks for your help

No, it's not. The header is 12 bytes long. What you have there is the header and one and a half data chunk. If you treat the rest of the file as sound data, you will be corrupting the other half of the second chunk and all the other chunks in the file, including the chunk that contains the actual sound data.
You should read up on the file format before you try to use it. The file is not at all arranged the way that you think it is.

Thank you that would explain why I have been having problems. I must be reading the wrong websites because that's where I got the 44 bytes from.
thanks,
Mike

I see. Yes, there is a 44 byte "header" that you can use when converting raw sample data into a wav file, but you can not assume when you read a wav file that it uses that exact format.
The 44 byte "header" consists of a 12 byte header, a 24 byte 'fmt ' chunk, and the first 8 bytes of the 'data' chunk. The rest of the 'data' chunk is the sound data, so by appending that you complete the 'data' chunk.

I have a program whereby the user adds items to a checked list box. Slowly the checkbox fills up with items. What I want to know is, when the program is shutdown, how do i save all the items in the list box to a setting or a location or a text file or something. My exit button is btnExit, the checkedlistbox is called clblist.
Thanks in advance for your help.

One way would be to write code for this on the ButtonClick or FormClosing event or something similar. You could save the items to an app.config file (which I think may prove to be unwieldly) or to a plain old xml file.

I know about the event. I could save to xml but i'd rather save as a string collection in the settings, problem is, i don't know how to go about it.

Which version of .NET are you using? 1.0, 1.1 or 2.0?
|
|
|
|
|
I'm using 2.0. Anyway thanxs for your help, i figured it out using a string collection setting, on load it fills the listbox with the collections items and on closing it removes all checked items then saves the rest to the collection. thanx again for your help.

Hello,
I have just had a error deploying a clickonce application. The error is below and has been solved
System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {10020200-E260-11CF-AE68-00AA004A34D5} failed due to the following error: 80040154.
The above problem caused me hours to solve. However, was solved my simply by doing the following: regsvr32 sqldmo.dll. to register the dll on the client machine.
I have created a deployment using the MSI, and never had this problem. But clickOnce does cause this problem if the dll does not exist and is not registered on the client machine.
Is there any way that you can use clickone to add this dll on the client's machine, so I don't have to go to trouble of registering manually.
When I publish this file I have added all the required dlls.
This is what I have done:
1. In the solution explorer | references | properties | set the sqldmo local copy to true
2. On the publish tab | Application File | set the publish status for the sqldmo.dll to include and required
3. Prereqisities | Added the .net framework, CR Reports .Net, MS Data Access components.
VB 2005 & SQL Server 2005.
Many thanks for any help,
Steve
