I am trying to insert a picture in the RTB but my system hangs when I try to do it... No error message... it simply hangs... I also get a tough time calling the Task Manager to end it...
This is the code that I am using...
Is it going into an infinite loop?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _

having problems getting one of 2 pictures displayed when I run the program. In a whole, this is a coin tossing program that, after the toss button is pushed, is supposed to show either a coin heads or tails image while also displaying True or False for heads or tails respectively. Additionally, a running tally of how many times heads and tails is displayed.The main issue right now is that when I press the toss button, no image is displayed, but True or False is displayed as well as the running number. After checking, running numbers correspond with the T/F results. The secondary issue is that a running tally is displayed, but instead of it being in a single or double digit increasing format, it shows up as 0011122223345666 as you keep pushing the toss button. I've researched books and the web to find out where I'm going wrong and to get more clarification on why it's not showing, but I haven't been able to decisive.
Public Class Form1
Dim randomObject As New Random()
Dim headscount As Integer
Dim tailscount As Integer

I am building an application using vb.net with sql server for a small company which requirs me to create reports that contain images. In my application I use microsoft report (rdlc) and I don't using any data source wizard, I just add empty datasets and bound them from sql data when the application loading. By doing this, I want to retrieve images from my sql field and display them in my reports. I've tried to drop an image control from the report items into my report, match its value with an image field in my dataset, select database source and choose a appropriate MIME format for it but it doesn't work.

View 1 RepliesI have created a basic word processor and come across a small speed bump; I have used a rich text box as the input, the user will be able to paste an image into it with no problems.
However I can't seem to find away of browsing for an image in a directory to insert into the rich text box.
i have an aspx web form with vb code behind. the form is a simple input form with a table with textboxes and a submit button. i am looking to be able to insert a captcha image into the table with an entry textbox and check the value entered against the image on the submit button.
i have found various 'helpful' bits of code on the net to explain how to generate the image. but none of them explain exactly how/when the image would get generated, how you can insert the image onto the webform where you want it to be, or how you can check the text input against that image.
Is it possible to insert an image to a directory from my resources when i start my application?
Im using this to create a directory when the app starts.

If System.IO.Directory.Exists(dir_name) Then
Exit Sub

I have a VB program that I'm trying to deploy. On my machine (the app works fine straight from VS), when I try to install it from the webpage, it asks me to setup .net. I only have a choice of repairing or uninstalling .net. I've tried both but both fail at the moment. The problem with the repair is, although it goes through the entire repair procedure, it then asks me to restart my PC, but when I hit 'restart', nothing happens. So I restart manually, but when I try again, I just have to go through the same procedure again.

I wrote an application on windows XP using visual studio 2008. Based on the .net framework 3.5. For some reason that I do not understand the application refuses to run on windows 7. You would think that if the .net framework 3.5 was installed on the windows 7 machine it would run.
View 10 RepliesI'm catching the following error in a publishing script (VB.Net) I'm running:
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
The code that fails is:
My.Computer.FileSystem.WriteAllText(path, content, False)
It runs fine for most of the files but some have a '~' in the path and those ones are all failing.
Just to clarify: i am using the full path an example of the path i am having problems with is "c:/websites/xml/myfile~test.xml" the ones that work are "c:/websites/xml/myfiletest2.xml"
I currently have this line of code which has been working for the past 6 months:
If IsNumeric(txtProductID.Text) Then

All of the sudden, no matter what kind of entry is put in txtProductID (including plain numbers), it fails! Is there reason for me to be going crazy over this?
I am currently using the AsyncFileUpload in my VB.NET web app. Locally it works perfectly, however on the server it fails to upload a small file (<9k). I can't even seem to debug this as in JavaScript handlers I have no idea as to how to get the error reason.

$get("<%=LabelErr.ClientID%>").innerHTML = "Unable to Upload file for the following reason: ", "<span style='color:red;'>" + args.get_errorMessage() + "</span>";

A VB2010 program fails to build because it doesn't recognise left() and right(). mid() works, though.
Microsoft.visualbasic.left() works ok.
Yet, in another VB2010 program, left() and right() work ok.
I have just finished my application using VB in Visual Studio 2005 and it works fine on my Win 7 development machine. But when I install and run it on an XP machine it fails with an unhandled exception:System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154.
I've googled the error message and the solutions seem to be 1) compile as x86 (was doing that anyway), and 2) register the dll on the machine But firstly I'm not sure which dll I need to register, and secondly I don't want to be going around registering dlls - the whole point of the installation programs is that it should just install and configure everything automatically..
