View 3 RepliesI am a newbie programmer. I have some code that needs to open a file based on what is contained in a variable. Example: If File.Exists(w) Then Dim q() As String = IO.File.ReadAllLines(w)
The problem is that I need the variable "w" , after readallLines , to have a .txt extension. I tried this:
IO.File.ReadAllLines(w & ".txt") but that doesnt work.
I have a config.txt file that has the following lines in it.
[MUSIC_PATH]=X:MultimediaAudio
[MOVIES_PATH]=X:MultimediaVideosMovies
[SHOWS_PATH]=X:MultimediaVideosTV Shows

I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
View 12 RepliesI have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String())
Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex)))
End Function

I have the following code that I am using to parse out a test file. I am getting variable conversion error in Sub Main() when I assign file = Read(). The return value of Read() is a TextFieldParser type. How do I assign the proper variable type to "file" so I can write the output to a text file?

just found out that replace(string does not do the same as string.replace when my string variable was an empty str the first one returns "nothing" and the second returns an empty string (as expected).just sloppy coding anyhow, it was a function that was converted from classic asp and never rewritten properly.

View 1 RepliesI am using the MODI DLL (Microsoft Office Document Imaging) because it has an OCR engine. That's working fine, but I'm having trouble capturing the resulting text into my own string variable (weird, huh). Modi has the result stored in the following Modi string variable:
img.Layout.Text
I've tried three ways to capture this value, only one of them works (not the one that I need to work)
(1) Dim txt as string = img.Layout.Text 'fails
(2) MsgBox(img.Layout.Text) 'fails
(3) M = new Msg(img.Layout.Text) 'succeeds
Method 3 (the only one working) is a custom msgbox I built in VB.Net, and it accepts a regular .Net string variable. I need Method-1 to work. The error thrown is this:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I even tried it like this:
(1) Dim txt as string = img.Layout.Text.ToString.Trim
Here's the complete code:
Dim doc As New MODI.Document
doc.Create("C:VCR.tif")
Dim img As MODI.Image

I'm trying to modify a program where there is a variable that stores all the specified file types in a String() variable. What I would like to do is to somehow append to this variable in any way if I want to search another directory or just grab another individual file.

View 12 RepliesIf I try to put a string into a Boolean variable such as this:
Dim testValue As String = "True"
Dim bool1 As Boolean = testValue
With Option Strict On I get an error and the suggested fix is to change the second line to:
Dim bool1 As Boolean = CBool(testValue)
This is fine, But - what are the advantages / disadvantages of doing this instead:
Dim bool1 As Boolean = Boolean.Parse(testValue)
Using VB.6, I am trying to assigning a value to a string variable but it causes an error. I am doing that in following way:
Dim a As Variant
a = "<div style="width: 400px;"><img title=""
sRndMessageNumber = "sNewMessage" & CInt(Int((3 - 1 + 1) * Rnd() + 1))
I want to Calculate a number between 1 to 3 and then call the variable sNewMessage2 for example. So how to convert from string to variable?
What i am trying to do is this:
Dim Name as string
Name = "Bob"
Dim Name.tostring as Integer
Which will create as variable called Bob of type integer.
But obviously this code doesn't work. So what is the real way to do this if it can be done?
