Thanks for the answer, Roath.
But this was not what I was looking for. I will try to be more clear.
I am pasting the "rtf" text with various styles from one rich text box to another rich text box. There I would like to change the font name and the size only and preserve all other styles. For example:
Text to be transfered : A brown fox is running. (font=Times New Roman)
Text transfered and formatted : A brown fox is running. (font=Tahoma)

Font name and size are changed but both the bold and underline style are gone.

Any idea?

How about using the lost focus event? Does this solution answer to what you need to do?

I need help on a vb or vb.net code to open a text file data delimited either with comma, tab, space or pipe and read the content to a recordset or an access database.

The one i have done make use of a fixed field but i want the code to dynamically detect the no of columns(fields) in the text file and create the corresponding no of fields in access database table. Since the text files come from different sources

Add a reference programmatically

Hi,

I am trying to write a macro that will add a reference to a Visual Studio project. I am using the following code:

DTE.ExecuteCommand("Project.AddReference", "path to the DLL I want to reference")

This fails with the following error message (in a messagebox): Error HRESULT E_FAIL has been returned from a call to a COM component

Am I supposed to pass some other information with the path to the DLL?

Thanks,

dlarkin77

Do a search for DShowNET on CP, it's in C# but the DLL can be compiled and referenced in VB, the projects are also in C# but it shouldn't be too difficult to convert to VB but it does exactly what you want.

Refer to Ed mention, if you want to convert from C# to vb.net, you can use this website[^].

If you've got an assembly written in C# why would you need to convert it to VB.NET? It is already an assembly. Also, while I'm primarily a C# developer I can quite happily converse in both because the majority of the what people "think of" as C# or VB.NET is actually the framework which is common to both. 45,000 common things versus about 100 differences. It isn't too difficult to pick up the minor differences between the two languages.

Thank you guys I managed to build an video recording application in vb, but now I need one more favour from you. You see this application is to be used by doctors while they are performing operations so that they can record the video and take photographs and save the file to patient record. Now as you know during operations they cant use their hands to operate a computer so they need a foot operated paddle which if presed continuesly for 3 seconds the video should start recording and if pressed for one second it must take snapshots. I need to know how can I do this either by using serial port or the usb port.

If newRecord = 1 Then
Q_IDTextBox.Text = newQ_id
newRecord = 0
Else
QueryQuestionaire()
End If
End Sub

Private Sub Q_HEADERBindingNavigatorSaveItem_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Q_HEADERBindingNavigatorSaveItem.Click

Thanks for your information but the link u gave me has no information about how to send or recieve data from remote machine via modem/internet ( I already know how to create application-using winsock over local area connection . . .)

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
