The blockers are there for a reason. You need access to a proxy outside the school network, which, if the IT staff has any brains, have blocked access to those too. You can NOT get around the firewalls and proxies your school is using.

There is nothing in the .NET Framework that does this. There are a few third party products that do do this, but they cost big $$$, on the order of $500 per developer.

Could someone please help me out with this problem I have been struggling with this past week?
Some background info:
I am trying to insert new row(s) into a datagridview called "CustSalesOpportunityLineDataGridView" (that is databound to a table called "custsalesopportunityline" in a master-detail form that contains includes the header info as well).
I have also created a generic product selection form that contains a datagridview called "ArticleDataGridView" that displays all the info and contains the filters that users need to efficiently search and filter out products. The dataset for the "ArticleDataGridView" is based on a view that I have created in the database.
On the "ArticleDataGridView" I have created a column called "Select_Article" that is a DataGridViewCheckBoxColumn. (false value = 0, indeterminate = 0, true =1). If the users want to add a particular product to the SalesOpportunityLine datagridview they should be able to check the checkbox for each desired row and then click the AddAndContinueButton. The Select_Article checkbox column is the leftmost column of the datagridview.
For each product that they have selected in the articledatagridview a new row in the "CustSalesOpportunityLineDataGridView" should be created and displayed as well as the articleID, name and Salesopportunityheaderid.
Is the code below written correctly to:
Test for the checkbox.checked=true on the first column of the datagridview
Write values to the "CustSalesOpportunityLineDataGridView".
Nothing happens when I run the code in debug.....
Private Sub AddAndContinueButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddAndContinueButton.Click<br />
<br />
For Each dgvRow As DataGridViewRow In Me.ArticleDataGridView.SelectedRows<br />
If Me.ArticleDataGridView.Item(1, ArticleDataGridView.CurrentRow.Index).Value = 1 Then<br />
Dim dt As DataTable = Me.SalesOpportunity.Tables("custsalesopportunityline")<br />
Dim dtRow As DataRow = dt.NewRow()<br />
dtRow("Salesopportunityheaderid") = NewSalesOpportunity.SalesoppHeaderID<br />
dtRow("articleid") = dgvRow.Cells("ArticleIdDataGridViewTextBoxColumn").Value<br />
dtRow("work_articlename") = dgvRow.Cells("ProduktnavnDataGridViewTextBoxColumn").Value<br />
dt.Rows.Add(dtRow)<br />
<br />
End If<br />
Next<br />
<br />
End Sub

I have about 400 zip files contained in a folder for a project at work and I need to get the csv files out. Is there a way to extract them all at once or will I have to get someone to do it!
What I would Ideally like to do is try and get it all automated as I will have to manipulate the csv files afterwards and load them into a database. Someone will have to do this every month and it sure aint gonna be me.
Many Thanks
The FoZ

You could unzip these things using the command line options of WinZip, or whatever you're using for .ZIP files, and write a DOS batch file to enumerate the files in the folder where they are stored. This batch file would use a FOR statement to grab each filename in the directory and launch WinZip with the correct command line parameters to unpack the files.

Thanks for the reply Dave. Looks like I had better learn batch files quickly.

Hi all,
I am trying to figure out how to make a presskey event fire.
The thing is I receive a message trough the serial port which i capture with datareceived event, then i parse the message and depending on the data i need to fire the presskey event. Like i may get the message left arrow key pressed -> how write a code that the application will act the same as if I would press the button on my keyboard.
Hope I was clear with my problem.
PS: I tried SendKeys.Send("{LEFT") but that doesn't work, i guess its becouse application is for smart device windows ce 5.0.
Thanks in advance
Greg

Are you able to process the received message correctly? Or do you need the key press from your keyboard to go back to the sending application? If the former you could simply call whatever method it is you need to run after processing the received message (if I've understood you correctly).

Hey,
yes I can receive message trough serial port I parse it and call sendkeys.send({DOWN}) ....
Btw: sendkeys works for smartdevice too but you need to download opennetCF... and reference the dll.
on active form the control from one button to another moves so the sendkeys works, but now i am having problem how to catch which key was sent trough sendkeys to active form...for example if lets say ESC key will be sent i need to do something...if I would be using keyboard i would use Keypressed event ...and if e.keys = ESC then
do something....
but how to catch this when i send which key is pressed trough sendkeys.send???
hope i am not to complicating but this is essential for my app.
Thanks

i am using a extensibility-shared add-in project in which i show a form when the power point slide show starts
Private Sub pptApplication_SlideShowNextSlide(ByVal Wn As Interop.PowerPoint.SlideShowWindow) Handles pptApplication.SlideShowNextSlide
Form1.show()
End Sub
I accept the key events and mouse evets on this form and when i press a right arrow key the form should remain visible and focus should come on the powerpoint slide so that when i press the right arrow key again it should fire the powerpoint's slideshownext event. but i am not able to remove the focus from the form and hence the slideshow next event is not getting fired. can any1 please help ?

You'd have to use the Win32 API functions FindWindow and SetForegroundWindow to activate the application then you use SendKeys[^] to send the keystrokes you want to send to the PowerPoint window.

You cannot talk to someone through a modem as if it were a phone. Not unless the modem you ahve specifically has this capability, which I seriously doubt. After the modem dials the phone number, you have to pickup the phone!

hi
maybe you can help me:
i want to make a password to be seen.
i want to replace these ***** with letters.
thanks
|

Are you trying to hack an application? If you are you won't find any help here. If you are develping some code and aren't sure there is a passwordChar field if you set it to 0 then the * go away. You would have to re-compile the app then the password should be visible.

I need to create browser compatability applications. And i need to disable forward and backward buttons. Is there any solution for this?
D.Willington

That depends on what you mean by a "browser compatability applications". What is this app supposed to do?
Disabling the buttons has to be done upon the creation of a new browser window. You cannot just disable the buttons on the currently open window.
These questions are better asked in the Web Development or ASP.NET Forums. Nothing in this question has anything to do with VB.NET.

You can write virtually any SQL you like in the SqlCommand. So long as you have the rights to create the tables you can doing by passing the relevant commands through to the database.

Hello!!! I'm currently modifying a program VB .net using SQL Server 2000. The problem is: How can i store a picture to the database. Through browsing the JPEG file and automatically view in picturebox, but i cant save it directly to the database. Is anybody help me. Is there any idea regarding this matter.
Daysee

Convert the source image stored by the PictureBox to a byte array, then store it in an image column in the database (you're going to need a parameterised query for that, unless you fancy converting the raw bytes to hex).
To get the picture out again, you will get a column which is a byte array. You can then convert that into a Bitmap which you can assign to your PictureBox.
