Global String Array Declaration In ActiveX Control And Package Installation Error
Apr 12, 2011I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

View 15 RepliesString Replace Does Not Work
May 11, 2010I have following code snippet that is supposed to replace the existing text in a local text file but instead it's just appending the new values on top of the file and pushes the older text down.
Here is the code:
dim sr as streamreader = file.opentext(path)
dim contents as string = sr.Readtoend()
sr.close()
Dim sw as streamwriter = file.Createtext(Path)
sw.Write(contents.replace("old value1", "new value")
sw.Write(contents.replace("old value2", string.empty)
sw.close()
What do I need to change to make it replace existing text rather than append?

String Concatenation Won't Work Using Class?
Jun 14, 2012I'm trying to concatenate two properties into one string like so:
public class thing
public property word() as string()
public property count() as integer()
[Code]....
This is what I want, but it doesn't help that its in the debug output...I need to put it into a single string. I've tried using a_thing.count(i).tostring, but it doesnt work. If I look at the arrays individually, they have exactly the contents I want. But I can't concatenate them. Does it have something to do with suppressing the new line that debug.writeline usually creates?

[2008] Third Connection String Will Not Work

Sql - Inserting Variables Into A Query String - It Won't Work
Apr 22, 2010Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.This works:
Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")
This doesn't:
Public Sub GetWASPAcr()
connection.Open()
Dim dt As New DataTable()
Dim username As String = HttpContext.Current.User.Identity.Name
[code]....
When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"
String Pointers - How To Get Name Output Parameter And Work With It
Jan 27, 2011My application uses a third party API. This API uses a few functions that returns a value by reference as one of the function parameters. Problem is according to their documentation, the value I am trying to get out of this function is a string pointer.
So if that made no sense, heres an example of the syntax of the function as shown in their documentation:
long ExampleFunction(long ID, long PropNum, char* name, long MaxStringLength)
Input Parameters: ID, PropNum
Output Parameters: name, MaxStringLength
Thats pretty much all the info I've got. Obviously they are not using VB.Net, looks like C to me. I want to get the name output parameter and work with it, but once I get this value, I cant change anything. I know this is because its a pointer (reference type?) but I am still at a loss as to what to do.
Why Does Sql Command Work As String But Not As A Parameterized Query
Jul 22, 2011[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.
