Is there a way to enforce case sensitivity in VB.Net file-names?
The primary issue that I am trying to solve is the difference in how Windows doesn't care about the case of a file-name, but other tools, like Subversion, do care about the case of a file-name

Supplier_List.DataGridView1.Rows(i).Selected = True
I am doing project in vb.net using ms access database I used one query like

I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.
I want to select one item in drop down list in ASP.NET written with VB.NET - I have values and texts in listbox like this:

Is not working and giving null for Volvo..
I want to know if a string exists in the list of array ignoring case sensitivity
I have the following code working for my requirement, but its checking case sensitivity. How can use it ignoring case sensitivity...?

If strList.contains(chkStr) Then

I just came across an interesting scenario. I have a class in C#:
[Code]...
As C# is case sensitive, this will treat the two variables A and a as distinct. I want to inherit the above class in my VB code, which is not case sensitive. How will the VB code access the two distinct variables A and a?
If I use code such as NewName = StrConv(OrigName, vbProperCase) to convert names to proper case, i.e. with initial capitals, I get unwanted results with Irish names like the following:
O'neill instead of O'Neill
O'grady instead of O'Grady

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]

I am used to C like languages such as C#. I added a list box with a list of names. In the code behind I added the below code. When I run the code I am getting the MessageBox but it will state "UserName favorite color is " but does not show the color. I thought it might be misspelled or non-matching names but this is not the issue due to the names being correct.

Overall, I'm wanting the IDE to force me to know what I'm doing if I'm throwing Ints around to mean Flags, or States and Strings around to mean Names, Propertys and Records.
this could be an easy one but I can't seem to figure out how to do this. I have a solution with
three projects in it. The main folder is fine but I want to rename the folders for two of the

I'm working on a project. It is a windows form app which has a webbrowser. The app navigates to a url automatically, checks the url's document, and jumps to another url (depends on the document). It works fine. But, now, the problem is the project needs check many urls, so, I'm trying to make it as a MDI form project. when the start button clicked, it create a control thread, in the thread, it launchs 10 MDI forms (within main form), each form does the work for different urls. once done, then launch the next 10 urls.
It works. However, I noticed that, although 10 MDI forms are open, the navigating part in their webbrowser seems run in sequencial. I thought these 10 MDI forms will load 10 urls at the same time, do the work at the same time, but I found that it seems they do load urls one by one, not at the same time.so, I did some research, it seems webbrowser can only be run STA mode. does it mean I can not use multithread to load different urls at the same time?basically, I want to have a multi tab webbrowser, and navigate to different urls in these tabs at the same time.
i am using My.Computer.FileSystem.RenameFile and i get error file already exist (obviously)
View 7 RepliesI have two projects that contain extension methods. One project is implemented using C# and the other is implemented using VB.NET as there are some things I can do in VB.NET that I can't in C# and I want to leverage those features in my extension methods. How can I name the projects to convey their meaning while at the same time differentiating that they are implemented in different languages?For the C# elitists:One of the features that VB.NET supports that C# doesn't:Doesn't C# Extension Methods allow passing parameters by reference?FYI: This doesn't work for reference types, which is what I'm interested in.

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.
It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.
Each time it runs, a program of mine creates an Excel document and names it using the current date ("Alerts from 29062011.xlsx" for example). The program gets run once a day,every day.The users have requested that I have the program delete the previous days Excel file each time it runs so that they don't take up space. I'm unsure how to do this though since, for example, if it is run on the first day of the month it would have to know
