Designer Codes Are Messed Up By VS
Apr 26, 2012I'm recently writing an app that is localizable and have several lauguage resources built within VS 2010 SP1. But now I came into a problem -- it seems that VS has modified one of the Designer.vb unregularly.The problem reveals like this. Whenever I want to change the main form's Language from Default into fr-CA (for eg, and with Localizable true), and after I save or run the project, then VS shows me with dozens of a same errors: 'Resources_ fr_ CA'is not a member of 'myApp'. The amount the this error I guess is depend on the number of controls on the form, but I'm not quite certain about that.Then I looked into the Designer file and found strange lines that were suddenly added by VS, they are somelike this two, not all these but commonly:[code]
The problem used to happened several times and it was passive before cos I can remove the lines one by one, using a text editor from outside. But now it is total nightmare, because, now whenever I set Language into French, the same problem MUST happen as saving the project. I can not debug or develop it with local language again, that is not any more a joke is it?
VS 2010 Messed Up .Net Framework
Mar 7, 2011I was messing with my program as I was having trouble getting it installed on machines without VB Express installed already. I adjusted the .Net requirement to 3.5 as I figured more people would meet that requirement without additional installs and now I get this error on my program when trying to change settings.Any idea how to get this set back up correctly.I'm on a Windows 7-64bit machine, using VB Basic 2010 Express.[code]

Content Of String Getting Messed Up When Converted From String To Stringarray
Oct 1, 2009I have a string which is xml data which is very nicely indented and well formed. Dim xmlstring as string I am trying to pass the above mentioned string to a Java Web Service but the input parameter datatype is string array. I am converting the string to string array as shown below localws.receiveNotification("TestQueue", xmlstring.ToString().Split(CChar("")))
As the datatype for the input parameter in the above webservice is string() array for some reason my XML data is getting messed up and lot of elements are breaking and appearing in two lines and my xml data is no more well formed.

An Array Of Objects - An Entry Will Be Stored In Serialports(4), All Other Array Elements Will Be Blank?
Jun 1, 2009I've come up with the following and it's partly working.
Public serial1, serial2, serial3, serial4, serial5 As SerialPort
Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)

View 2 RepliesObject Array To Byte Array - Marshal.AllocHGlobal Fragmentation Query?
Jun 14, 2011I didn't think it fair to post a comment on Fredrik Mörk's answer in this 2 year old post, so I thought I'd just ask it as a new question instead..NB: This is not a critiscm of the answer in any way, I'm simply trying to understand this all before delving into memory management / the marshal class.
In that answer, the function GetByteArray allocates memory to each object within the given array, within a loop.Would the GetByteArray function on the aforementioned post have benefited at all from allocating memory for the total size of the provided array:
Dim arrayBufferPtr = Marshal.AllocHGlobal(Marshal.SizeOf(<arrayElement>) * <array>.Count)
I just wonder if allocating the memory, as shown in the answer, causes any kind of fragmentation? Assuming there may be fragmentation, would there be much of an impact to be concerned with? Would allocating the memory in the way I've shown force you to call IntPtr.ToInt## to obtain pointer offsets from the overall allocation pointer, and therefore force you to check the underlying architecture to ensure the correct method is used*1 or is there a better way? (ToInt32/ToInt64 depending on x86/64?)
*1 I read elsewhere that calling the wrong IntPtr.ToInt## will cause overflow exceptions. What I mean by that statement is would I use:
Dim anOffsetPtr As New IntPtr(arrayBufferPtr.ToInt## + (loopIndex * <arrayElementSize>))
I've read through a few articles on the VB.Net Marshal class and memory allocation; listed below, but if you know fo any other good articles I'm all ears![URL]..

.net - Array.Sort() Doesn't Correctly Order Target Array
Apr 13, 2012I'm using the following code to read in a highscores file with the score written first and the player's name written to the next line, and then display the top 3 scores or fewer if there aren't 3 scores written to the file. A highscores display should have the scores sorted with the highest first so that's what this program tries to implement.
Array.sort() isn't doing a damn thing. In fact, the program's not even reversing the arrays like it should either. I've tested array.sort() this way with the names and scores arrays given explicitly and it works fine. I thought maybe it was still reading the data as string even though it's declared otherwise but it rounds off decimals when I change the array type to Integer so I'm pretty sure it's not that.
I have no idea why reading the data in from a file changes how it's sorted. My teacher didn't understand what was going on either. Does anyone know what's going on here?

Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
