I cannot open and read files larger than 32k. This sub is used by both user-dialog and drag-drop operations. Files smaller than 32k are processed without error. Files greater than 32k result in the ErrorOpenFile warning with "Overflow" as the err.Description being displayed.

A query concerning opening and saving a file.i have two commands, one the opens and another that saves [the same file].i'm using the StreamReader and StreamWriter methods.issue is this:if i comment out the open code, the save works fine.if i comment out the save code, the open works fine.if i let both run together, i get an error, usually with the save saying that the file could not be accessed. note, before anyone asks, i do close the file after saving or opening what could be the problem? open works fine, because it usually happens prior to the save, and then save process cannot access the file..?
View 3 RepliesHere is my code:
Public Function ReadBinaryFileLarge(strFilename As String) As Byte()
Dim position As Integer = 0
Dim bufferSize As Integer = 4096

Is this the correct way to go about this problem? If not, how should I attack it?
I am using Visual Studio 2008. While opening some of the .resx file, it is giving me error that "The operation cannot be completed. Invalid Pointer". What can be the possible problem and solution?
View 1 RepliesI've never seen this error before; and apparently (According to DIC) the number would have be bigger than -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, to this this exception (I'm using an Integer, but I've tried Int64, and the same thing happens).
This is where the exception is being thrown:
Dim localPort As Integer = (tcpRow__1.localPort1 << 8) + (tcpRow__1.localPort2) + (tcpRow__1.localPort3 << 24) + (tcpRow__1.localPort4 << 16)

I highly doubt that that the integer that is being parsed back is greater than, either of those numbers listed above. I've tried using Int64, and even removing the << operator, but it's still throwing this exception.
We have a VB application, which will get input from the user, post it to HTTP url and get the result from it, assigns it to objects and displays it to user.
In this flow, users are getting Run-Time error 6(Overflow). But this is not happening all the time. Iam not able to reproduce also?Would there be any other reason for this, apart from normal reasons like assinging a higher value to lower datatypes.
I'm trying to make a grade calculator that can determine the minimum grade you need to acheive a desired grade. I'm new to visual basic, and I'm trying to figure out why I keep getting the run-time error '6' message.

could you tell me, why I get the stack overflow error on this code?
Dim ev As Double = datum.Year * 365 * 24 * 60 * 60

The double datatype should be enough.

View 4 RepliesI have a major problem. Things were going great until I came across this little bug(?) which has thrown a stick in my spokes. As I will demonstrate below, it seems that when defining certain numbers Visual Studio will throw an overflow error.
Dim T As ULong = 14774537964905701134 'Overflow error in the IDE
Dim M As ULong = ULong.MaxValue '(18446744073709551615) we are below the maximum value so it should work, right?
The one solution I have found is that we can use the following declaration instead.
Dim T As ULong = ULong.Parse("14774537964905701134")
However, to make matters even more complicated the value in question is unknown and must be compiled using CodeDOM so using the Parse method isn't an option. Unless there is some way I can determine if that value in particular will give me an overflow error.
I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.

I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.

I have 19 .CSV files that hold engineering data in single and multiple Arrays.I would like to loop through the Directory that contains the files and open each file, fill the array and close the file and continue to the next in Alphabetical order.

[Code]...
I am writing a program that stores filenames, along with a lot of information about the files in a database. I need to be able to open these files in three different programs from my application. One of these programs, AutoCAD is the default program for the files, but the other two are more difficult. These two need to open the file in a program that is not the default for the file type. Eventually, I'd also like to allow users to point the application to the instance of AutoCAD, MasterWorks, or FeatureCAM that they want to open. I have found articles that explain how to open a file in a default application and articles that tell me how to open any application with a file name, but only 1 suggestion of how to control the program used to open the file. For some reason I cannot get AutoCAD to recognize the file I feed in if I use this method though, so I think it's wrong. This is the method I found that doesn't work:
Start("D:Program Files (x86)AutoCAD 2007acad.exe", file)file is a variable that contains my file name. Since this works fine when I take the program path out, I know the filename is correct, but AutoCAD says it is not.
A simple WebKitBrowser1.Navigate(localfilehere) doesn't work for some reason.
I tried adding "file://" to the URL but that didn't work either.
This seems ridiculous but is this functionality really not present?
