I have this code within a button: If TextBox1.TextLength = 3 Then MsgBox("Please enter 3 numbers followed by a letter. For Example 001A")TextBox1.Text = "" Me.Refresh() End If Although if the user enters 3 numbers only, I want the rest of the code in the button to be ignored so that it doesn't proceed.

View 5 RepliesI'm trying to replace text using this method:
Add each characted to a String list (List(Of String)), execute the replace function for every type of character (for example: Text = Text.Replace("A", "0AA") Text = Text.Replace("a", "1AB")), but there's a problem: it replaces the text, but it replaces those replaced characters too, so when I replace "A", it will result something like this: "0AAB AAA 0AB"... (a long text)), and then add the characters to the result string
how make the application stop and start the replacing of the next character

I have been experiencing a problem with one of my Try Catch blocks. Specifically, I have a block of code that inserts data into a db using a stored procedure. There is a problem within the code getting one of the parameters to the SP. I know what the problem is and how to fix it. My issue is that the Try Catch should be stopping any further execution of code once it catches the error. I have verified that the error is being caught and that it sends the exception to my label used for error reprorting. However, instead of stopping future execution and displaying the error it rolls over the label assignment and continues to the next piece of code in the calling procedure. In essence, it is as if there is no error occuring at all.To give everyone a point of reference, I call a sub-routine from a button click event. Within the sub-routine I have my Try Catch block with the SP code. I am NOT using Try Catch Finally. It is simply Try the SP Catch ex as Exception and End Try.
View 2 RepliesI need to be able to edit vb.net code using visual studio without stopping the debugging executable.How can I go about doing this? If it's impossible, how can I code and reload that code without stopping the executable? I know of scripting languages like Lua, but I fear the implementation of another language within the VB is unnecessary to save me the trouble of stopping the executable. The issue is that starting and stopping this executable can take a very long time, and I need to be able to edit the code quickly and frequently.

Private frames As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.
How do I post this HTTP REST request using HttpWebRequest and System.Xml.XmlDocument in vb.net
<tns:request command="hello" xmlns:tns="http://www.xxyyzz.com/xx/yy/zz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />

I am currently developing an application using VB.NET in which I am using the REST WebServices. I have been able to do the basics with REST, however, I have not been able to add an attachment (more specifically upload a file, using REST which gets attached). I have done extensive research online, but so far I have not been able to find any working examples in VB.NET. To actually upload the data I use System.Net.WebClient. The following VB.NET code does the important work:[code]As you can see, the postString is converted to bytes and then uploaded to the server. However, I do not know where or how I should be posting the raw attachment itself. The documentation for the service we are specifically using states to use a variable "attachment_ 1," which I added to the postString variable, but I am not sure what the next step should be. Should the file be converted into bytes and appended to the postBytes variable?

For this program im using http method post to recieve messages from the server, when its waiting for a new message to be sent it locks the program up. No biggie, ill just thread the sub... Bad idea... I also have functions "send", "Connect", "disconnect". All on threads... i looked at task manager it started getting up to 100+ threads. I dont know much about threads but that just seems way to much. they will die off and the count will return to 20 but id like to find a different way of keeping the program from locking up but not having 100+ threads.. Little off topic: i used a user control. The only problem now is on the tab, its not anchored with the rest of the form... how do i accomplish this?

I'm trying to write a program which allows a user to determine how many 'I's will go into a text box. (i.e if they select 10 then the text box will look like I I I I I I I I I I ). I'm writing a program where if I click on one of three buttons then a number of 'I's will disappear out of the text box. Button one will subtract one 'I', button two will subtract two 'I's, and button three will subract 3 'I's. I don't know how to get the information from the button into the program to subtract the correct number of 'I's. If I press button one, and I have:
Dim OneI as Integer = 1
How do I get the 1 in the OneI variable into a calculation outside of the btn sub, like into a function or a different sub?

I found this code on here while doing a search and would like to be able to use it but it was written in C and I dont know much about that (don't know that much about VB.NET either but trying to learn)[code]What I do have is a text box where a user enteres a desired number of US dollars to convert to three types of currency.I know how to convert the string entered to an integer so the calculation can take place. What I don't know how to do is modify the above code so that the results will show up in the correct text boxes after each calculation (yes I know I have to convert the integer back to text).If someone could show me how to do the first Select Case I can figure the rest out.
View 12 RepliesI have the following controller actions:
<HttpGet()>
Function News() As ActionResult
End Function

Function News(ByVal id As Integer) As ActionResult

I want it to be smart, and go to the first if I have no ID in the url, and the second if there is. I got the following error:
The current request for action 'News' on controller type 'MarketsController' is ambiguous >between the following action methods:
System.Web.Mvc.ActionResult News() on type TradeChaseMVC.MarketsController
System.Web.Mvc.ActionResult News(Int32) on type TradeChaseMVC.MarketsController
So, I thought if i explicitly created routes without the id parameter optional, like this:
routes.MapRoute( _
"Default2", _
"{controller}/{action}/{id}",
New With {.controller = "Home", .action = "Index"},
New With {.action = "^[a-zA-Z_]+$", .id = "d{1,8}|"}

It would work, but it doesn't same error. Now I know the simple solution is to call my methods different things, but i don't want to do this. I was also thinking of creating an attribute to prefix the ID method, to check for ID being there, and if it isn't dont allow that method, but I can't get this to work either.
This is what I am trying but it doesn't work. The idea is to rest the caret position at the beginning after I hit enter and the conents od Textbox1 are deleted

What is the best way to access a Rails 3 REST-ful web service, developed using standard Active Resource techniques including HTTP authentication over SSL, from a VB.NET consumer?Consumer can be .NET 4.0 if that is necessary.Are there any .NET libraries yet that can bridge the gap?
I have already come across links like this [URL]..web-services/), which use Linq.XML or XML.XPath to parse responses and generate post data for REST-ful web services. I have in fact coded a system similar to the one at that link, except for a different geo-coding provider and using XPath instead of Linq.
I am trying to write some code to serialize the XML returned by the Bing Maps REST location query. So far my code parses down to the "ResourceSet" level and then screws up. am trying to have the "ResourceSet" element parsed into an object of "LocationResourceSet", since this is a location query and the "ResourceSets" vary depending on the type of REST call
