A number like 1,000,000.33 is written in another country as 1.000.000,33
which computer setting do I need to read to understand which type of number annotation is used on the current computer?
is there a way to convert those numbers in a neutral way??
i am getting the xml using readxml method. And then display the data in datagrid. But number type columns comes as string type in the dataset. So when datagrid displays , sortingdatagrid columns is not correct. For example it sorts like this:
Salary
1180
12133
[code]......
I want to be able to calculate and display the current Frames Per Second on a computer.Now I do have a bit of code, though, it seems to be locked at 65fps (screens refresh rate?).Here is what I have:
'calculate Frame Rate
Public Shared Function CalculateFrameRate() As Integer
If System.Environment.TickCount - lastTick >= 1000 Then
lastFrameRate = frameRate[code]....
on the fps form, it is just a simple form with a label in it.
i want to set a default number and you type in a textbox a random number it should tell you whether it's high or low ,and when you typed in the right nmber it a lable should says something like you win .And also how can you change PART of a lable by typing in a text in a DIFFERENT FORM
View 6 RepliesI'm trying to pass some parameters into a data annotation, and it is rejecting my named parameter. It's the same exact syntax in Microsoft's documentation for the TableAttribute, except in the documentation they have an uppercase N, but intellisense on the parameter in VS asks for a lower case n. It looks like the constructor was updated, but the tooltip wasn't, because this is what shows up when you get the syntax prompt: And I needed to be able to specify schema. But now I've found another way to do this. Why I was trying named parameters in the first place; because this wasn't working. Apparently I missed trying this syntax, which works.
View 2 Repliesi have a column in datagridview composed of numeric as well as aphanumeric. What i want is when the user sorts the column, it will be sorted according to its number value, 1,2,3,4,5,6,7,8,9,10. However it my current module, the program sorts basing the first digit of the column. like 1,10,11,12,2,3,30,31.
i was thinking of converting the type to number so that it will be arrange properly, is this possible in the datagridview to covert type? because i saw only a readonly property celltype? i have also tried casting it in the sql query itself to INT but it did not work.
in the sense that MVC does not complain about my protected inner abstract Metadata class, and the model validation still works:
Partial Domain Object, generated by a tool:
Partial Public Class SampleDomainObject
Private _id As Integer
[code]....
I did this because I didn't want to have to implement actual properties with backing fields, getters, and setters in VB.NET for the Metadata class to keep the maintenance to a minimum (I'm on .NET 3.5, no auto-properties for me).What I'm worried about is that having a protected abstract inner class could be confusing to others using this domain object outside of MVC (my domain objects are part of a shared data access framework).
Is there a dataannotation validate rule for a collection based property? I have the following
<DisplayName("Category")>
<Range(1, Integer.MaxValue, ErrorMessage:="Please select a category")>
Property CategoryId As Integer
<DisplayName("Technical Services")>
Property TechnicalServices As List(Of Integer)
I'm looking for a validator that I can add to the TechnicalServices property to set a minimum for the collection size.

Take a look at the snippet above. On the third line, I'm trying to set a multidimensional array to the type that the current class is. How can I get the type of the class that I am currently in? I'm using VB.net so all .net examples are acceptable.
Does ASP, C#, VB.NET have a way to retrieve what line its on in code as its processing commands?
Example
1 <%
2 response.write("Your on line " & retreiveCurrentLineNumber)
3 %>
Output: Your on line 2
I am using data annotations to validation my class properties. A requirement has emerged to store the validation error messages in an external file from which they would be loaded into memory at runtime.I thought I'd be able to load a colleciton of error messages from an XML file and then set ErrorMessage:=[StringVariableHere] ... but apparently that doesn't work as you need to use a constant value.If I store the errormessages in a Resource.resx file then those error messages are compiled into the project and can't be loaded at runtime - or am I wrong?

View 1 RepliesHow can I do some code when the user changes what line the caret is on? So something like:
sub textbox1_lineindexchanged (byval ....) Handles Textbox1.Lineindexchanged
'do code based on the current line
end sub
I am using a richtextbox, just I always used it so I just call it a textbox.
Traditionally, class/type name is literally spelled inside its definition.
Public Class MyCustomClass
Public child As MyCustomClass
Public Shared Function Clone(ByVal original As MyCustomClass) As MyCustomClass
End Class
This is not a problem most of the time; C-languages even use class name as constructor methods' name. But consider a generic declaration:
Public Class MyListOfIntegers
Inherits MyCustomList(Of Integer)
End Class
[code]....
This scenario has 2 issues. The first one is that constructors are not inherited, and you have to provide pass-through wrappers in every derived class, — this is quiet dumb, but tolerable. The second issue is more severe: derived class inherits CloneMe() method which returns MyCustomList(Of Integer) , not MyListOfIntegers ! Every returned value must be manually DirectCast 'ed for further use with methods that expect MyListOfIntegers . This issue, together with the first one, renders inheritance of generic class almost useless.
So I need a "MyClass" alternative for static type-binding inside type definition. In case of generic type that is referencing other compound types, task could be accomplished by adding second parameter to type section:
Public Class MyCustomList(Of T, TList)
...
Public Function CloneMe() As TList
[code]....
But since we must reference our own type, it would create an infinite recursive loop of additional typeparamlist arguments. How can this be resolved, aside of creating separate classes without generics?
I'm Trying to make a piece of software where You enter a number and the computer measures the length of the number, and then generates random numbers to match the human number. It will then count the number of guesses and the time taken. However it always comes up that there was a infinite loop "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll". I have searched up how to do this and I can't seem to find out how. I think I just put my wording wrong when looking it up. My Software Has Has 2 TextBox, 2 Buttons, 6 labels (4 just to make it user friendly) and a timer.
Here is the Code:
Public Class Form1
Dim TimeTaken As Integer
Dim GuessesTaken As Integer

I'm supposed to make an app where computer generates a random number using a function and then the user has to guess the number. If they get it right, they see a picture.... If they get it wrong the loop keeps going until ten guesses are up.. I'm running into quite a few problems...
1. I don't know how to tell if the photo will show up if the number is right because right now I have it set to false in the form, so it dosen't show up but in my loop I included the code that SHOULD allow it to show up if both numbers are the same.... Not sure if this is correct...
2. I have a textbox that is supposed to keep track of the number of guesses but the message automatically becomes Game Over and the guesses go up to 11 as soon as I click the Are You Right Button?
3. When I try to debug, my app freezes and I don't know why...

I've seen threads on this topic posted before but they didn't come up in the search that I did. What's the best way to get a computer id code of some kind that is unique for each computer so I could use that to create a unique software activation code?Does Visual Basic have any staements that can give you this kind of information.

I'm doing a project now. I'm having a problem on getting specific file type from my computer using the .getfiles function.
Here's my codes.

Dim filepath as String = "C:"
dlgOpen.CheckFileExists = True

What I wanted to happen is when the openfiledialog prompted and once I've selected the file, the file information I've specified above must show on the application as a label. But nothing appears. The file name only appears on the text box beside the open button. It should also appear above the button and the text box as a label. How could i possibly do that? And how could I select just one file at a time from a folder with 150 other files in it? When I use getFiles, it only gets all at the same time everything that's in the folder even if i've only just selected one file.
I need designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"
View 7 RepliesI have written an application for my family business. It works fine when I try it on my computer, which I've used to write the app. But it gets the "Data type mismatch in criteria expression" error when I try to save data on the computer where the app is installed and will be used on.I don't get it. Is it because of the operating system?
View 6 RepliesI have been given an old dll and the assignment of accessing it through C# .NET 3.5. I believe the dll was originally built with VB6, but am not positive. There is no documentation or source for the dll aside from an example for how to use the it in VB6. I have been able to succesfully access it through VB.NET 3.5. Example code for accessing looks like this:
myLib = CreateObject("MyLib.api")
myConnection = myLib.CreateObject("NameOfConnectionObject")
myConnection.do_something("abc")
There are several different objects that are created from the library and all of those objects have different methods. I tried using different dll reading tools, but all the export methods show up as garbage. I also tried importing the dll in visual studio, but I get an error stating the dll is not accessible and/or not a COM object or assembly. So, I only know about the methods from the old documentation which is sparse. how to access in C# and/or find out more about this mystery dll?
i cant understand what constants are.

I have a modem that I've been trying to communicate with only to discover this....went to the modem properties and queried the modem.....
AT+FCLASS = 0,1,8
AT#CLASS = ? COMMAND NOT SUPPORTED
(And I had been trying to use AT#CLASS = 8 all day).So, what does this mean?That the modem is automatically in voice mode (or will automatically choose it's own mode) and forcing it isn't necessary?Still no luck with the connection response messages either -- RING, etc.All I can do is make a call and the called number will appear in a textbox.
