• ADHDsowhat Validating Textbox

  Hello. A question please. In a version of VB that I don't remember exactly, a textbox had a property called "numeric" which avoids characters. In VB2005 is there something like this Thanks... Simply bind your data property to the .Text property of the MaxkedTextBox. Alternatively, you can programatically set the MaskedTextBox.Text = MyNumber.ToString(). Jim Wooley http://devauthority.com/blogs/jwooley SQlServer is my table. I retrieve a decimal data of a table and I want to put it in a maskedtextbox. Thanks...

• HuWu listbox items

  How can program a list box so that when a certain item is inputed the font color changes Drawing items with different colours is very straightforward once you set OwnerDraw to an appropriate value. The following uses Spotty's example, with the error corrected in btnDelete_Click, and will colour alternate rows with blue and red. Public Class Form1 Dim F As New Font("Arial", 8, FontStyle.Regular) Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ListBox1.DrawMode = DrawMode.OwnerDrawFixed End Sub Private Sub BtnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click Me.ListBox1.Items.Add("Add an Item" & Lis ...Show All

• Marcello Gribaudo How can I remove vbCrLf from a string?

  How do I delete all instances of vbCrLf from a string Thanks in advance. I'm not sure how you splitting the items Dim crlf() As String = {vbCrLf} Dim line As String() = strContents.Split(crlf, StringSplitOptions.None) I found that if I had a CRLF at the end of each line and did a split using VBCR but not stringsplitoption parameter that it would leave the lf character in the string array items. Chnaging to the above seemed to cure the problem. You could also do a string replace with the character with a space prior to deleteing the white space. This you would use on the string array items. For reading lines from a text file try something along these lines: Dim tfr As ...Show All

• raghuramaiah FileUpload - How do I trap maxfilesize problems

  The fileupload control works well for files < 4MB (maxrequestlength), but if the file is larger than this the program fails with: - the page cannot be displayed, or Server error in '/xxxxx' application Maximum request length exceeded How do I trap this so that I can return a better error message The failure occurs before the Page Load from any callback, so I can't see any way of trapping the error, and I haven't seen any event or property of the Fileupload control that I can set to say "Do this when Max Request Length is exceeded" I don't want to accept larger files, I'm happy to live with the limit.

• JohnDoe1 Automatic Namespace generation in VB

  I've just finished a dll written in VB. I've never bothered with namespaces much until now, but this is a bit complex, so I've arranged it into sub-folders, with a top-level class, a few sub-classes (and base classes), and other classes that hang off some of the sub-classes. Every class has the same "Namespace Handler" around it. Looks garbage in the object viewer - every class is under the root namespace. When using the object however, it looks fine, i.e. you only see the correct sub-sub-classes hanging off the correct sub-classes, etc. However, one of my colleagues who talks C# had a look at my code, and commented that my namespaces were not declared properly, then we discovered that when coding in C#, the namespace line wer ...Show All

• Al Christoph Bizzare problem! IDE won't accept any changes.

  Something very bizzare is happening and I have no clue as to why. Whatever changes I make to a form in the IDE whether it be adding a button, removing a button, or changing the text (title of the form), it will show in the IDE designer. But when I run it, it's as if none of the changes were made. A button I removed is still there and the code behind it still executes although I commented that code out. Saving the files doesn't fix it. Closing the solution and reopening it doesn't fix it. Exiting Visual Studio altogether and restarting it doesn't fix it. And restarting Windows XP doesn't either. It's as if my application is stuck where I left it last night. When I reboot everything, launch Visual Studio, and open the sol ...Show All

• cpurick Permissions Issue

  I have a service which copies files from a local diretory to a remote, I set the permissions on the remote directory which to start with was the local machine to Users (DEVELOPER\Users) - DEVELOPER is the machine name everything worked fine I then used a directory on our Windows 2000 server, under the security tab it states the Everyone has full control yes the images do not copy over. It has to be a permissions issue as it works fine locally just not sure how to get around this The default is full trust, surely this is sufficient Two things to check: 1) Which account the service is running as 2) What the permissions for the network share are (th ...Show All

• Marzullo C# as operator equivalent

  Is there a VB.Net equivalent of the C# as operator Here is some C# usage of the operator- SqlConnection conn = Dts.Connections(Connection_Name).AcquireConnection(Nothing) as SqlConnection if (conn != null) { // Do work as we have a valid object } You use it for casting, but it will never throw an invalid cast exception, the result is left as null. I am familar with CType in VB.Net but that will throw an InvalidCastException if the types do not match. As a workaround I have found TypeOf - Dim connectionObject As Object Dim connection As SqlConnection connectionObject = Dts.Connections(Connection_Name).AcquireConnection( Nothing ) If TypeOf connectionObject Is SqlConnection Then c ...Show All

• JoraPJL Create Web-like Forms as Windows App

  I have used VS 2005 to create a family-based web site ... about 100 pages/forms consisting of mostly text with some graphics thrown in for interest. I have no intention of putting this out on a publicly-accessible server but instead had anticipated burning everything onto CD's and then distributing that to family members so that they could view the site on their own machines (XP Pro SP2) using IE. In inquiring on this forum how to do that I am told that that is not feasible and that instead I should have created a windows app and simply deployed that app to the family (via CD). That's fine except for one thing ... I don't know how to create a web-like app as a windows app. For example, as I create the app I want to be able to easily highli ...Show All
