I don't have any idea why it's throwing that exception, but you don't even need your CharSet value. In VB.NET, CharSet is Auto by default. In C#, it's Ansi.
There are really only two settings anyway. Under Windows 9x and Me, the Auto setting will pick Ansi. Under everything else, Auto picks Unicode.
Though, you still need the Sequential LayoutKind...

Thanks Dave,
You are right. Its an optional Param. I dont ned to mention the value to be Auto. But if i dont do it, i will not be able to get back the Type of File from the Function. It returns a Blank String. I specifically have to mention the charset for that.
Please refere to the following article for reference:

Hi
I use Access database in my vb.net project. when I run program in debug mode I get correct display of date time value in a table of a table adapter I use.
The form of displayed value is supposed to be short date ( ex. 4.1.2008 ). but when I run the program as an independent program then the value is diplayed with time like 4.1.2008 10:35.
Does anyone know how to resolve this problem.
Bye

Putting a webbrowser in a form and thinking you wrote a browser seems to be a common pursuit. I am not sure you can do much to block popups without writing a browser plug in. In any case, IE does a fine job of blocking popups, at least with the google toolbar installed, it does.

I need to communicate with an sd card thru VB.net how can I do that? any suggestions?
BiG RaLpH
|
|

U can directly connect by using ports and device I/O
You do not have to directly connect to the card reader..
The card reader comes with a SDK and driver interface which lets u do it..
Good Luck
|
|
|
|
|
thx for ur help but the card reader is a USB Device.
what can I do?
thx again

Dose it not have a SDK along..
I had connected with a smart card not with SD card...
i hope the SDK will do the trick
The long way is identify the device ID given by OS and try to connect..
I am not having any samples to give ... sorry for that..
I had connected to a Tablet with the tablet dll available in the SDK..
Thats all i can tell u..

|
|
|
|
Thx I will try it.
I will let u know if it works.

You can't communicate with the card. It's considered media, not a device.
The card read/write is the device.
But that's neither here nor there. When inserted, the contents of the card will be exposed as part of the file system, usually a FAT32 volume. You can use any of the normal file/volume operations to get at the card.

I want to read it as a binary file all of it this will help me get to where i want in the file.
any Ideas on how to do that?
thx a lot.

Use the normal I/O operation to read the file inside the SD. Use the object File under the namespace System.IO

If you are using a DataGridView or something similar you can usually access the SelectedCells() property. SelectedCells(0).RowIndex gives you the row index of the first selected cell.

What error do you get?
The following could be issues with your code:
poonams wrote: MessageBox.Show(item.SubItems(0).Text)
item is not instantiated
poonams wrote: MsgBox(LstRecord.SelectedItems(1).Text)
or
MsgBox(LstRecord.SelectedItems(1).SubItems(2).Text)
or
l1.Text = LstRecord.SelectedItems(3).Text.ToString
Most likely the maximum array subscript of SelectedItems is less than 1, ie., you have only selected 1 item from the list.

I currently using VB.NET and RichTextBox Control, when i want to save the data it works properly, but why the cursor move to the top?
Thanks

Try some thing like this which i use for the multi line text box
txt_box.SelectionStart = 0
txt_box.SelectionStart = Len(txt_box.Text)
txt_box.ScrollToCaret()
Good luck
|
|
|
|
|
Your code i think it not work properly because the cursor will be go to buttom of TextBox control,
I mean whereever cursor focus after saved it still focus the same place.
Thanks
