Gmail integration in VB.net

3-Dec-06 4:20

Well, you've got a bit of a problem. Just putting a ProgressBar on a form doesn't do anything. You have to update it with, well, progress.

If you're using the File.Copy method, you'll never get that progress. It's a blocking call that doesn't report anything during the copy.

In order to make a progress bar work, you have to copy the file yourself using file stream methods. You know...open a file read some of it, write that to another file. Well, that's where you update the ProgressBar.

You get the size of the file first, start copying the file, track how much of the file you've copied and update the ProgressBar as you're copying the file.

Like the others have said, you can even move the copy operation to another thread so your UI stays responsive.

I am using vb.net 2005 and I would like to be able to pragmatically bring up a new Gmail compose window logged in to a gmail account that I will supply the username and password to and then fill the form out pragmatically including:

To field, CC field, BCC field, Body field with HTML text, add multiple attachments.

Has anybody done this or know of a component or URL protocol out there that I can accomplish specifically this with?

Best Regards,
Brent Stringer

Have you tried looking at the Google API. Most of Google's services use a standard set of API that a developer can use in their programs. However, they do impose limitations on at least the searches available with the searching API, and the developer must register to use the API.

If you are using SQL Server 2000, you can query table sysobjects.All user tables have the type column = 'U'

You can query syscolumns based on the ids of the tables you retrieved from queyring sysobjects

WebClient.DownloadString() after POSTING data

Hey all,

I have the folling code to post data to a php page. However, I'd like to retreieve the response from this page after the posting and save it to a file. The response should just be plain-text XML. (IE, it'll echo out an XML file in plain text as the source). Is there a way to use something like the downloadstring(URL) on this AFTER posting up the data, in order to capture the response?

Thanks,

Mike

   Public Function PostToWebUpdate(ByVal postData) As Boolean<br />
        Dim Client As WebClient<br />
        Try<br />
<br />
            Dim dataBytes As Byte() = Encoding.ASCII.GetBytes(postData)<br />
<br />
            Client = New WebClient<br />
            Client.Headers.Add("Content-Type", "application/x-www-form-urlencoded")<br />
            Dim returnedBytes As Byte() = Client.UploadData("http://www.mysite.com/folder/file.php", dataBytes)<br />
<br />
            Dim myResponse As String = New String(Encoding.ASCII.GetChars(returnedBytes))<br />
<br />
            Return myResponse = "SAVED"<br />
        Catch ex As Exception<br />
            MessageBox.Show("Error: PostToWeb: " & ex.Message)<br />
            Return False<br />
        Finally<br />
            Client.Dispose()<br />
            Client = Nothing<br />
        End Try<br />
    End Function

Your probably didn't make one. It's one of those little quirks that doesn't have an explanation. Though, that may change with the release of SP1 for Visual Studio .NET 2005.

Within Application Hook?

I would like to be able to know when a key is pressed within my application. I've been looking at different options and came across keyboard and mouse hooks. The examples I've seen (unfortunately for me written in c#) seem to only be for global hooks. I'm not interested in what happens outside of the program I'm writing, just when the program is active should it listen for a keypress. It would be nice if it didn't matter which control had the focus either. The idea is to create a commandline that becomes activated instantly when a certain key is pressed.

I'm not sure if hooks are the right direction to go for this or perhaps there is something simpler that I can use.

Any help would be greatly appreciated.

Thanks,
David

You don't need a global hook for this. All you have to do is set the Form's KeyPreview property to True, then handle the Form's KeyDown event. It'll give you all the keystrokes going to that form, even it's child controls, before the controls see the keystroke.

Hi,

Are there any good, methods of creating a routine in an application, making the application trialware, until a key code has been entered. Must stop application running after x uses or x days after original install date.

Thanks, Andrew Robinson.

If your familiar with the settings in properties you could have a boolean for first use, when the program is first run set to false and set another setting to the current date, then each time the program is run check that date and compare.

Both of these settings could then be made redundant by a boolean setting that is set to true when registered. Sorry about not providing code, but this might give you a start.

With one of my applications I have an encrypted file named "Activation.dat". This file contains 3 lines of code.

{ProgramEdition}
{Time activation file created - day of year)
(days left of the trial period)

When the program starts in the main procedure I read in all this data and make sure that the days left not equal to less than 0 and that the day of year is not before the current date of the computer. If the file is missing or the days left is less than 0 then I write to the days left field 'expired'. The program will then fail to execute. This is a very basic form of trial protection that I am using in the beta release of one of my pieces of software, I will be updating it but this is what I have right now. I would suggest a strong encryption procedure, I use a OneTimePad rolling encryption algorithm, but algorithms like RSA, DES, Rijndael should be sufficient.

For further protection you can also have the software end on a particular date.
