The file locations for a setup package using Standard Edition? I have added an .xls file to my project, marked it as Content and as Copy Always in the properties for that file. The XLS file I added to the project is from my user Apps folder in the Roaming sub folder. Other simple .TXT files are in my UserMy DocumentsData folder and each file is also maked as Content and Copy Always. When I create the setup package all goes well. I have a setup.exe and an .msi file. When I test it by installing it on my PC of course the program knows where the files are because it's my PC. In the program folder created as C:Program FilesMyProgram I find the .exe plus the XLS and TXT files, but these XLS and TXT files are not used from the program folder. How might I know if an installation made by another user on another PC elsewhere is going to load files in their user apps or user documents? I need to be sure that the additional data files deploy to the correct location (whatever I want that to be) on a remote PC.
View 3 RepliesI have a panel (A) which has movable panels (B) inside of it. How can I get a rectangle that contains all of the child panels (B)?
I tried to loop through the controls in the panel and get their x y height and width, find the highest, most to the right, most to the left, and lowest and put those numbers into a rectangle, but no luck.
VB2008 I have a panel in which I draw some graphics. Parts of the codes which I have successfully wrote & drawn are shown below:
Dim scaleX1 As Single = CSng(Me.pic_pcg.Width / 1.355)
Dim scaleY1 As Single = Me.pic_pcg.Height / HGT
'
e.Graphics.ScaleTransform(scaleX1, scaleY1)
[code]....
I want to add some labels and textboxes in the panel so as to add remarks & captions to certain parts of the graphics.How do I set or modify the "scales ?" of the locations of these labels & textboxes so that they will be placed correctly, corresponding to the above scaletransform/translatetransform/rotatetransform.
I want to get all picture box locations. I am remotly creating them so i couldent just get each one individualy.

I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?
I have recently gotten my hands on a free, open-source IMAP connection API.So far, I have been successful in creating a connection to one of my accounts.Where I'm getting stuck is retrieving folders and/or emails from those folders.Does there happen to be anyone here that is familiar with this API, or even Gmail (particularly the folder structure for IMAP)?
If not, here is a link to the DLL that is listed on sourceforge and the company's website that created it (if you feel like testing):
Koolwired
Sourceforge - Koolwired API
I have created a test account so feel free to use the code below without worrying about username/password issues; I'll just delete it when I'm done with it.Here is the code I have made so far for making a connection:
Dim gSession As New Koolwired.Imap.ImapConnect("imap.gmail.com", 993, True)
Dim gAuthenticate As New Koolwired.Imap.ImapAuthenticate(gSession, "imap_test@serysoft.com", "imap_test")
Try

When I run that code, I get an error that states:System.NullReferenceException: Object reference not sent to an instance of an object. (The bold line in the above code).
Now, I'm not sure exactly what that means. Does that mean it tried to access the server and "INBOX" doesn't exist so it gets returned a NULL value? Or is it possibly the coding itself?Maybe the Gmail folder system is weird due to the fact they use labels (even though from what I have read online, the labels act as the folders in the IMAP system).
What is the problem in below code.
d Public Sub filltextbox(ByVal dlist As String) Dim tb As TextBox = CType(Page.FindControl(dlist), TextBox) tb.Text = "hello" End Sub

Is there a way to make a grid out of a picture so when a certain slot on that grid is clicked an event will happen? It cant be an exact location, because that will be too hard to click. but a relative location would be perfect.

View 3 RepliesI have a collection of locations for a sales person, allowing them to send an item to multiple locations. I want to start reading at index 1 since I am using a collection. I saw an example where you can say something like "+ 1" (e.g. myitem.SelectedIndex + 1) to skip the first record. How can I skip the first record for the following:
Public ReadOnly Property Customer() As ICustomer
Get
Return CType(Me.CustomerList.Item(Me.CustomerNumSelected), ICustomer)
End Get
End Property
I tried to say Return CType(Me.CustomerList.Item(Me.CustomerNumSelected + 1), ICustomer) but it returns an error saying "string cannot be converted to a double". without the + 1 in there, I get an error that says "collection index must be in range 1 to size of collection".

I'm however stuck on how to make my markers (PictureBoxes - two per player) move along the board.So heres my problem; I have 40 slots where the picturebox can be moved to (eg picturebox1.Top = 324, picturebox1.left=243). Now moving to these slots are determined by the roll of a pair of dice. How can I assign a variable preferably an integer for each slot so when the dice is rolled I can just do a little addition as to where the markers can be moved?

View 7 RepliesGreetings,
My app saves a bunch of stuff to an XML file. This is my line of code-
Using writer As XmlWriter = XmlWriter.Create("C:vdx2kMWSREEXTReportsInboxTK" & frmCitation.txtCiteNumber.Text & "Traff.xml", settings)
So that saves it at that specific location.
I need to duplicate the XML and have it also save in another location. I've been at this for days, Googling, searching, trying different things and now I need to turn here for help.
Any ideas?
I want to show some forms but I want them to appear on specific locations . The problem is I don't know how to specify the coordinates . Using :
frm.Location = "0,0"
or
frm.Location = (0,0)
tell what is the correct syntax ?
And more thing : when a form is maximized or minimized , it looks like "flying" upwards or downwards . Is it possible to stop that visual efect ?
