Write A Simple Windows Form That Will Make It Easy To Record A Voice Message Before Uploading It To A Remote Web Server?

Oct 2, 2011

I'd like to write a simple Windows form that will make it easy to record a voice message before uploading it to a remote web server and sending the URL to the recipient(s):

[URL]

Currently, the user has to use Sound Record to record the message, use an FTP client to upload it to a web server, and finally, use an e-mail client to send the URL. I'd like to combine those three features into one.

Error Message - Form Cannot Be Modified

Dec 30, 2009

Every time I modify something on a form (add or delete controls , modify their colors etc) , when I debug the program (with the Play button), I get a message saying: The file C:........MyForm.vb cannot be modified at this time .

Why is this happening? I have noticed that the only way to bypass this problem is to save before debugging , but that is not convenient because I don't want to save something that I haven't decided yet. One more thing that I have observed is that this only happens in projects that have been created with the Upgrade Wizard (from VB6). This never happens in new projects. Does anyone know why is this happening ?

Asp.net - Display Specific Error Message On Custom Error Page

Sep 1, 2011

I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />

I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.

Is there a way to make the actual error message appear on this custom error page too?

Simple Form With A Usercontrol

Aug 25, 2010

Description of problem: I have a simple form with a usercontrol on it. There is a drop down box with a list of departments in it and a button, this is all in the usercontrol. I pick a department then press the button to view the employees in a listview for the department picked. All worked fine until I moved the code for drop down and button into the usercontrol from the form.

The data is taken from oracle database express 10G edition and I am using a cursor package (CP) and I pass parameters from the code to the oracle procedure within the CP. One of these parameters is the selected department from the drop down list (which I have picked) and my code does not seem to be picking up this parameter, it keps saying that the bold bit of code below is nothing:

myCmd.Parameters.Add(New OracleParameter("n_dept", OracleDbType.Varchar2)).Value = usr1.cmbDepartments.SelectedItem

Everything else seems to be fine. Because it is not picking up the selected item then the dr.read (no data by the looks of it) is false and it just falls out without populating any employees for that dept in the listview.

Does anyone care to take a stab at suggesting what might be wrong? Why won't it pick up the selected item in the user control I have just picked it in?
