If I have a small double in vb.net like this:
dim x as double = 0.00000003
A conversion to a string would produce a E-presentation (3E-7). in debugging the value it will be shown as full number (0.00000003). How can I get the full number in a string?
Using vb.net 2003 asp.net 1.1. I have this C# function that I converted and I gettinga squiggley saying full and partial not part of string, this is converted from a .cs file.
Here is the function, maybe I'm not seeing something:
Code:
Public Function RefundTransactionCode(ByVal refundType As String,
ByVal transactionId As String,
ByVal amount As String,
ByVal note As String) As String
Dim caller As CallerServices = New CallerServices

I have a method that takes 2 string arguments. One that contains a normal string and one that contains a string with one or more wildcard characters. I've tried the following code:
Private Function DoesMatchWildcardString(ByVal fullString As String, ByVal wildcardString As String) As Boolean
Dim stringParts() As String
Dim matches As Boolean = True
[code]....
The I realized that it won't work properly. If I have ABCD as a normal and A*CD as my wildcard string the match will work even if my normal string was CDAB, which is not what I want.
In my project I need to use a 190 very long strings with different number of characters (4-60).I want to mark them in a short form with the numbers 001, 002, 003 ... 190. Is there an easy way to display the full name of the string when I choose a short name ? Of course, I do not want to write 190 times "if - end if" and also I would like to avoid a complicated database. Onenew Visual Studio 2010
View 17 RepliesI have a project which has a table with a list of stores. Originally the store code was a string of 3 and was padded so 1 would be 001 etc. I have had to increase this column to 8. The problem is when I read in data from a XML file the store code is padded so it looks like this '500 ' rather than '500'. This is now causing a major problem when I do a comparison.Is there a way to it does not auto pad to the full string length?
View 5 RepliesI am trying to log the contents of an object to a text file. If I do a debug.print of the object itself in the immediate window, it prints all of the values of the object's properties:
?mDb.DatabaseOptions
{Microsoft.SqlServer.Management.Smo.DatabaseOptions}
AnsiNullDefault: False
...
UserData: Nothing
However, I can't seem to access this as a string in code due to a type mismatch. I assumed I could get this information using the .ToString method, but all that returns is the object description with none of the properties or values:
?mDb.DatabaseOptions.ToString
"Microsoft.SqlServer.Management.Smo.DatabaseOptions"

But whenever i populate the trr programatically the above problem starts.

This is Q2 for today, as I seem to be coming up with all these little glitches I can't figure out!!I have a webcontrol, which I use to show a PowerPoint presentation - by using webctl.navigate("c:MyPresentation.ppt").This works perfectly, and my presentation shows exactly as desired.However, sometimes, when I close my application, the Powerpnt.exe process is left running.Is there any way of programatically forcing this to close if it has been left open, or am I not disposing of something I should (I can't find anything along these lines when running powerpoint through a web control)?

View 6 RepliesI want to embed a PowerPoint presentation with narration, timings and the presentation PASSWORD in my application so that it will automatically start the Pesentation and enter the password, when a button on the form is clicked. I want to do this so that the PowerPoint presentation can only be viewed from within the application, where the password is embedded in code, and cannot be run by just finding the PowerPoint presentation file and clicking on it to run it.
I do not intend for the user to be given the password. I would imagine that i could use process.start to run the presentation, which can be put on the target computer at the time of instal, but I don't know how to handle the password with code on the button.
I've been working to refactor my code and ended up with a quite clean main BLL class that has only a few manager classes that pass information between eachother. They handle separate tasks/areas like socket connection, data, etc. It's only one instance of each of these manager objects, so I believe maybe the base layout is a structural singleton (?) ..but not sure. This seems to give quite good oversight and a clean separation of PL/BLL as the main form only access the BLL through one instance of a single class. But now I'm trying to figure out how to lay out the presentation layer. So with this I would like to understand a few points: Do you have all controls as members of the form class, or can you make sub classes where some controls only exist on lower levels? Like for example if you have a tab where all controls only interact with each other, and not the rest of the form, would it then be possible to make this a separate class that holds both controls and additional logic ? The first problem I get when trying this is with the events, as if I simply move an event handler method to another class than the form class, I get the message: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.What does this mean? and is there an easy way around this? I would like to understand how a slightly more complex PL is designed, so I know what direction to move in for studying/developing this.

View 1 RepliesIm currently working on an n-layer application that does alot of database work.90% of all database queries are updates, and inserts and I want to be able to view the results of my query in the presentation layer.I was thinking of creating a QueryResult class that has a few properties like QuerySuccessful (boolean), Message (string) - holds success or error message, and optional field to hold any additional data that may need to be passed back to the presentation layer.So I guess my question is, am I going about this the correct way by creating a QueryResult class, and passing that back up through the layers to my PL?

I created a presentation which runs in kiosk mode as a PowerPoint Macro-Enabled Show. Now the problem is, that the presentation resets itself to slide one if there is no user input for 5 minutes. How do I disable this feature?
I am using Powerpoint 2010 (Version 14.0.6112.500 (32-bit))On a side note: I already found an Add-In (KioskAssistant) which enables me to increase the time before the slide is reset. But this change is only done locally for my machine and not saved into the presentation itself. So this not a sufficient enough solution if I want to ship my presentation to my client
