• Brendan Grant VB6 Image control in VB2005 used as feedback device in a picture

  In VB6 I used Image controls to give visible feedback when the mouse moves over a 'sensitive' area in a picture: set the borderstyle to fixedsingle and set it back to none when it's outside. I am looking for a simple equivalent in VB2005. VB6 Image controls are transparent, but anything I can find in VB2005 in the form of (user-) controls is opaque (right ) and requires a lot of hassle with the underlying image. So the functionality I am looking for is to let the user know where on a picture he can click, for further info and whatever. Without ruining the picture (a bitmap in a picturebox on a panel). Should be easy, but can't find any help in the help. Help! In have a lot of these areas and I want ...Show All

• AndyJ_PS Fill Several Combobox with the same values from database

  Hi, I have 15 Comboboxes in a form and I have to fill them with the same values from a database table. If I use the same datatable to fill them all at the same time, everytime I select a a value form a combobox, all the rest show the same value !!!!, I don't know why this happens. So I tried to use a function to open a new datatable for each Combobox datasource and works fine, but the problem is that my application turns slower when loading that form. This is my function when all ComboBoxes take the same value when some of them is selected: Public Sub FillCombos( ByVal xComboArray As System.Collections.Generic.IList( Of Windows.Forms.ComboBox), ByVal DBConn As SqlClient.SqlConnection) Dim i As Int16 ...Show All

• edward1028 SMTP / Message ID

  Is there a way to retain the generated message id from the built in System.Net.Mail.SmtpClient I don't think so since the message-id will be generated and assigned by the SMTP server (not the client). So the Message-ID header value is empty until after the message is submitted for processing. Right.. but if you monitor the process using ethereal, you will see the SMTP server respond with the message-id.. does .Net do anything with this response or store it anywhere I don't think the SMTPClient provides any access to this response. I guess you could use a TCPClient and submit the message yourself... would probably take a little work to work out the trasmission details but that would let you capture any response from t ...Show All

• Virdee Putting a function into another function

  I can't find a clear answer to this problem. What am I doing wrong I am having problems writing this piece of code. it is supposed to be a customized function that has within it another function. It is supposed to see if content is Non Numeric. If it is non numeric, a messagebox is displayed, if it is not the message box is not activated, and the software continues to the next argument. Here is a sample of the code: Function TextIsNotNumeric( ByVal txtBox As TextBox) As String If Not IsNumeric(txtBox) Then MessageBox.Show( "input is Not Numeric - Re enter" ) End If End Function 'and this part is where I call the code in the main program Private ...Show All

• imj How do I show a confirmation box instead of a MessageBox?

  I am trying to find a relatively simple way of showing a MessageBox with a "Yes" and "No"(Confirmation box). Can anyone help me please MsgBox is the VB6 way of showing the messagebox. But in vb.net it is replaced with MessageBox. So If You are working in VB.Net then use it's provided method. But there is no problem in using MsgBox because it is still supproted by .net. Thanks nobugz. Create your own dialog form and place the "Yes" and "No" button there and set the DialogResult property of the button accordingly. and use this form to work as a message box. and show it calling the ShowDialog Method.

• rwerner Data Validation in DataGridView

  I am attempting to validate the data entered into individual cells of a datagridview. I am using the CellValidating event of the datagridview, however the 'sender' element appears to be the 'datagridview' and not the individual cell. Is this the best way or is there a better event to use You can use e.FormattedValue to get content of the cell. Have a look on the code below, I paste it from MSDN example: private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { dataGridView1.Rows[e.RowIndex].ErrorText = ""; int newInteger; // Don't try to validate the 'new row' until finished // editing since there // is not any point in validating its initial value. if (dataGridVie ...Show All

• Worf Enable Application Framework - Disappeared - VS2005 Pro

  Hi all, Everything was fine until yesterday... Now if I double click My project (Visual Basic 2005) I get to the Application page but the "Enable Application Framework" and "Windows application framework properties" does NOT show. I need to enable the framework to change a couple settings. How can I make this checkbox appear again If I create a new project this option will show perfect. I think the cause of this problem was that I copied and pasted a form, renamed it I got lots of errors and I think I got Application.Myapp corrupted (opened it and saw lots of chinese characters). Closed the copied form, deleted it and I was able to get rid of all the errors (I think Application.Myapp is ok now). I've go ...Show All

• ChaosBlade My.Computer.FileSystem -- kinda light, isn't it?

  This isn't a specific How To question, but more a philosophical one, so I may be in the wrong place... It involves the My.Computer.FileSystem, which--if I read my indicators properly--seems to be poised to completely replace the older FileOpen, FilePut, FileGet, etc. and I say this because the latter are referred to as being "provided for backward compatibility". This usually means it won't be there at all in another version or two... Don't get me wrong, I love progress. Find a way for us to stop inventing that dang wheel over and over again and I'm your best buddy. But when I look deeply into My.Computer.FileSystem, just about everything there pertains to Text files. There are two functions left for binaries, ReadAllBytes() and WriteAll ...Show All
