As things are now, I need my program to store x number of file locations. My first approach was to use an array, however as i do now know how many files there will be, i am forced to use redim preserve. That is not very effective and I have therefore started using a StringCollection.
or is there some smart way to store these paths, that I have overlooked?
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 --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

Hi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?

I have a generic question regarding file paths and user interfaces. I am trying to build a user-interface to accommodate various file locations. I typically build interfaces which deal with files on drives. As such, I use a directory tree for this. I usually work with files on local drives. However if I wanted to ensure that all file locations were dealt with I would want to ensure that I was accommodating files in all drives (local, network, mappped etc.). I am assuming that the treeview would support all of these drive option.
However if the files are on a sharepoint site or in some other type of enterprise content system, then am I correct to assume that these file paths will be URLs? If so, then am I correct to assume that a directory tree is not the correct control to use for these locations? Should I be providing a textbox to the user and prompting them to enter this URL? Or is it better to have the URL loaded into a ListView or ListBox (i.e. "My Connections") and then provide these as options via a dropdown box. I am trying to picture a typical user interface. Is it a directory tree AND a text box/dropdown box.
I am doing setup project in VS 2008. I used custom action to select file from local drives. On the button click of custom action form, I am launching Open file dialog as ofdGetNetPath.ShowDialog When I run the setup on Vista, and click the button to open the openFileDialog, it hanged, form becomes non responsive and I have to cancel the setup.
on debugging I got following error "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."
so I used the following code:
Dim ofdThread As Thread ofdThread = New Thread(New ThreadStart(AddressOf ShowOpenFileDialog)) ofdThread.SetApartmentState(ApartmentState.STA) ofdThread.Start() Private Sub ShowOpenFileDialog() Me.ofdGetNetPath.ShowDialog() End Sub
now on button click, OpenFileDialog is shown but it is not showing Mapped drive or Network location... what should I need to do to show the mapped drive or network locations?
I am using this code to parse an html file for image locations:

How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.
I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?

In my VB6 application I would store the user's numeric index/socket number/whatever you'd like to call it as the Key, however, in VB 2008 I can't seem to find where, or if, the numeric index is stored. If this isn't possible then does anyone have an example of how they store user connections using some numeric index as the key of a hashtable?

I am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

View 3 RepliesI am having a problem storing an image as a Blob in a SQL linked table. Our system uses an Access 2002 frontend and linked to a SQLServer2000 database. I have a form that I want to display a unique client jpeg photo for each client record. Our client HIPAA concerns means we have to store the image not the path in the database field. I am using an Image control on the form. Initially I have been able to load an image from a Windows Dialog into the control and save the path no problem.
My issues are surrounding how to actually save and load the jpeg as a BLOB in a VBA byte Array after the image has been loaded to the form from the dialog box.(Is there some sort of binary conversion needed or does the Append and GetChunk methods handle all this)?:
All the code examples I have been able to find on the subject have a line of code to set the Image control's data source to the open recordset with this statement ---> Set imgDBImage.DataSource = rs. Does this statement work with VBA because DataSource does not show up as a property of an Access 2002 Image Control. So how do I point the Image Control to the table field which contains the BLOB in VBA code?
Finally, how do you convert the string path of the image to binary for storage in a byte Array in VBA. I have the syntax for a VB 6.0 which is..... .Fields("ImageBLOB").AppendChunk bytBLOB. Is the .Fields portion of the code relevant in VBA to tell what table field to write to and does the AppendChunk method handle all the conversion?
you can use the My.Settings that VB.Net 2010 can offer. Go to Project > Project Name Properties > Settings and there you can add variables. The value of the variable is saved even after you close your program.A program that will show the text you saved last time is the following:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If My.Settings.X<>"" then MsgBox(My.Settings.X)
