I have a third party referenced dll which I have set to 'copy local' in my project.
How can I make the location of that .dll not be in the same directory as the built exe, but in a folder called 'Resources' within that directory?
I've been using the following method to store the primary key value of whatever record is being referenced. I would then call the Content.Id method to retrieve that value for sql commands.
My question is - is this good practice? One other told me I should make a session item instead.
This is my ContentDA class
Public Shared Property Id() As Integer
Get
Return _ContentId

View 2 RepliesI have created an updater for our clients application. The way the updater works is to download all the updated files and store them in a temporary folder then check the file hashes. If everything is ok it will copy the files to the applications installation folder. Once this is been completed it will delete all the updated files in the temporary directory.
My problem: I am looking for a directory that will be available for XP, Vista, and Win7. I was thinking about the 'temp' directory.
does someone know if it is possible to build an application that store data in a folder locked by truecrypt where the application
1) create the encrypted folder
2) pass the password to read/write the data?
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Is there a magic number over which it is better to start splitting the folder? for example below "10.000" (invented number) files can be stored in one single folder, while above that it is better to start storing files in multiple folders.

I have the following projects:
TradingProject (my code) Has reference to TradingLibrary, and to ApiLibrary?
TradingLibrary (my code) Has reference to ApiLibrary
ApiLibrary (3rd party code)
I'm making several projects (like TradingProject) that communicate with a software through use of an existing ApiLibrary. But I want to push generic methods into a library I write: TradingLibrary.
Still, I would like to use some parts of the ApiLibrary directly from TradingProject. However, I then would need to pass an object (of an ApiLibrary class) into a method in TradingLibrary. Where the object should be recognized. However I assume this will be a problem, as TradingLibrary use it's own reference to ApiLibrary, so it will not be recognized as the same classes? Is there some way I can "forward" the ApiLibrary reference from TradingLibrary to MyProject, such that they will use the same reference? Or do I need to duplicate the classes and inherit from ApiLibrary for each class? Like:
NameSpace TradingLibrary
Public Class SomeClass
Inherits ApiLibrary.SomeClass
End Class
I guess that would work, if I do it for all classes I need, but is there perhaps some simpler way I'm not aware of?
I'm co-developing a vehicle information system that reads and presents data from a communication bus. Signaling information on the bus is stored on some kind of database (from the dark ages i'd guess) from which it's only possible to get data out of by extracting a xml-snapshot. Since that wasn't bad enough, someone in upper management thought it was a great idea to treat different parts of the system as different projects (it looked really nice in the organizational chart) which lead to more databases...It is now my responsibility to merge these xml-files into one and before I start banging my head against the wall i thought it would be a good idea to check with you geniuses if there's any neat solution to my problem.The structure of the xml is somewhat like this:
<data>
<frame ID="1001">

I have been using Excel in vb.net for years and no problem but I have a new app and nothing is working. First I can't get Microsoft.office.interop referenced anywhere, which was weird. Then I can't instantiate Excel App.. Dim pExcel_App as New Excel.Application -- this gives me error "New cannot be used on an interface??But I can do this..Dim pExcel_App As New Excel._ExcelApplication -- where did this come from?Then I can't put anything into cells Dim wkbSheet As Excel.Worksheet wkbSheet.Cells(1,1) = "Title" --- this give me an error "Expression is a value and therefore cannot be the target of an assignment"
THe really weird thing is that I have an old app open at the same time that is just fine with all this code. AND the intellisense is different for each cell.The good one sets is as a range, the bad one says it is an object???I re-installed the MS PIA's but this didn't help.
I decided it was about time I learned about accessing Microsoft Office products via VB.NET. I started with Excel and it all worked fine, I could create a new Excel Application, open a workbook from file and read from the sheet then close it all down again no worries. However, when I turned to Word...things got strange. Using the code provided below, every time I run it an instance of Microsoft Word opens itself on the desktop (with no loaded content). I didn't have this problem when using Excel with similar code, so I have to ask..what gives? Is there a way I can stop MS word opening at all? At the moment it just flickers for a second (it opens when I open the document, then when I call the Quit method it shuts down a split second later)[code]...
