Import Xlsx File Into Using TransferSpreadsheet When Path Is Constant But Filename Is Variable
Oct 1, 2009
I use the followoing code to import an xlsx file into an Access 2007 table. It works fine when I enter the exact file name.However, part of the file name is a date which will change every week.The file location does not change,just the date in the file name.[code]I've tried using a wildcard but I get a Run-time error 3011.Db engine could not find the object. Make sure the object exists.

How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName
Properties.Settings.Default.Save();

I suppose technically this isn't .NET specific but I suspect this is something to do with the registry and I'm using .NET!I'm trying to find out how to get the fully qualified path relating to a file type.For example, the system knows that to open a PDF file it needs to launch C:Program FilesAdobeAdobe Reader 10.0Readeracrord32.exe
I've had a good long search through the registry and found a lot of references to the adobe path probably too many - and I've edited them to try and "break" the process so I can identify which one is used to discover the path but with no luck. I'm assuming this has something to do with HKEY_CLASSES_ROOT?

How can I remove the actual file name from the path returned by the FileName property of an Open or Save File Dialog?
All I want is the path to the file without the file name.

I am trying to replace a string which is actually different from line to line in a text file. I want to end up with a filename but without the path. For example:
My text file contains:
C: est estingmorefilename.mpg

W: estinglocation estingmore estfiles9.mpg

in my program, i use that code for getting the file path of a process, once it gets the path, it is put into a list view which has details like the task manager. the code works fine the first time, but with a little bug that is, when it reaches the vhost of my program. For some reason, it just copies the file path of my program even though the process has changed. After the code has gone through, i want it to refresh the list so as doing the same as when loaded...so I let it refresh and once again it copies the path of the vhost, but this time it has basically taken over every process' location. So in turn, I only get returned my programs location, for something like the task managers location, where it would be like "C:Windowssystem32skmgr.exe"
Here's the
VB
Private Sub frmmain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Process As New Process()
Dim Count As Integer = 0
[code]....
The refresh code is frmmain_Load(Nothing, Nothing) just to make things easy for me right now, while i get that part of the program going. To me it seems to be working fine, but why it does that what it does, im not sure. as you can see, the process changes. and Ive even checked it through run time, and each and every time, the process.processname changes.

I am trying to trim the path from a filename. With the following code, it returns "My Documents" where I should be getting "Test.txt". if I change the 1 to a 4 I get what I'm looking for, but that's not going to work if I'm working with a file deeper into subdirectories. I need it to display the name of the file regardless of location or file type.

I got an easy one this time How can I get a file knowing the path and the name of it, but not knowing the extension which I need to get. You can see at the moment I use this silly code which finds and opens some main filetypes for me, but if I could get hold of the file extension just by using the filename and the path I could open any document or image...

I would like to create a filepath and assign it to a string (so that it can have yet more added to it later on in my program) the code takes (well i want it to but it doesn't) the name of a drive selected previously and then adds this to a string to create a string variable that refers to a file. and then (as usual) i want to use thes files and display them in a combobox but i want to only select files that have a pre selected 2characters at the front. I have got this code so far:
' search for filer drive NETAPP-1
For i = 0 To frmDatabase.drvDB.Items.Count - 1
If InStr(frmDatabase.drvDB.SelectedText(), "\Netapp-1malika", CompareMethod.Text) Then

I've come across a very basic problem which I'm sure has a basic answer.Forgive me but I haven't programmed in years and this just a hobby of mine..My problem is that I need a drawn object (say an ellipse) to move to the cursors location when I click. Imagine an adventure quest style game where you view your character in birds eye view, and it moves according to where you click on the map.I can draw the image fine, and move the image around fine - it's more so the formula I'm using which I'm a little stumped on.I have certain requirements though.
1. I need a timer that constantly updates the drawn object's (lets say character from now on) location. Each tick will essentially be the character taking 1 step towards the cursor's location.2. At the end of each tick of the timer, it'll will invalidate the form/control to invoke the paint event, and of course, the objects location will be be updated.It sounded simple enough to create a linear equation based on the objects original location and the location of the cursor when I click.However, that will not give it a fixed speed.If say for example, the gradient (rise/run) between the cursor location and objects location is very steep, the object's y-velocity will be greater than that of the x-velocity

Any way to assign a binary value to a vb variable? All of the obvious choices don't work. I've tried prefixing with &B, appending with b but nothing seems to work.For clarification, what I was looking for (which does not appear to be possible) was how to assign a literal binary number to a variable, in a similar manner in which you can assign a hex or octal number. I was just looking for a more visually engaging way to assign values to a flag enum.
Dim num as Integer = &H100ABC 'Hex'
Dim num2 as Integer = &O123765 'Octal'
Dim myFantasy as Integer = &B1000 'What I would like to be able to do'
Dim myReality as Integer = 2 ^ 3 'What I ended up doing'

We are using a custom API in our project which provide an attribute for class fields/members which lets the interface to present a popup of some range values like "On/OFF" and pass the corresponding values of the choice to our code. The attribute requires a string array to know that values.We have many enumerations defined for these ranges,We are thinking to use Enum.GetValues() kind method to get a string array for this method.However, As we know the field declaration do not allow dynamic values in the declaration? so is there any other of doing same thing in efficient way.To clerify the problem i will write the examples below;
Current Working
<RangeLookUp("On:1","Off:2")> Public ASimpleRangeVariable As Integer
While I wanted to do like this or kind of
<RangeLookUp(SomeMethod())> Public ASimpleRangeVariable As Integer
Public Shared Function SomeMethod() as String()
'use Enum to get all the items as string values forexample Enum.GetValues & enu,.GetValues [code]....
Where SomeMethod suppose to return string array to be passed in the RangeLookup constructor.Which means if we change enumeration then we don't have to update the declaration.i know there are better ways to do it but due to some custom API, the ground is limited.

The selected path is assigned to a public variable which is used with concatenation to crate folder for saving user input data. How can I change the path string to a constant so the user can run the program again without having to run setup routine unless they want to change the save location?

suppose I have variables named A1, A2, A3 ... B1, B2, B3 ... Z97, Z98, Z99. I have a certain operation I want to do using each one in turn. I CAN write a line of code for every single variable, but this will get pretty tedious. I'd prefer it if I can make a function that takes the letter and the number as arguments. So, if it gets the arguments "E" and "10" it will perform the operation on variable E10. What is the syntax for this? say a simple operation such as: result = E10 * 3 Is the syntax any different if I use constants instead of variables?

Using vb.net 2008 I have a form with a PDFViewer control. I pass the filename and path to open the pdf. When the form is closed, AcroRd32.exe is not destroyed. It remains in Task Manager even after I've completely closed the application. The more pdf files I open, the more memory used. How can I destroy? I've tried setting the control = nothing, ctrl.dispose but neither is working. What am I doing wrong?

This is the code I have set up to scan a directory of files:
Dim fileArray() As String
fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is:
F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be:
book_troubleshoot.html
Is there a way to do this without parsing through all the array entries to trim off the path?

I am a new developer in general and decided on VB.NET for my first language. So, I decided that I should write a basic FTP client since the types of apps I plan on developing later on will incorporate file transfer. I imported the chilkat dll as a reference to my project since the FTP seems to work great. Anyhow, I've designed my program with separate interfaces for sending and getting files (see attached screenshot).
The problem here is that I use an openfiledialogbox to select the local file to transfer to an FTP server which this populates the textbox with "C: ext.txt", but chilkat wants the filename without the C:, or I receive an prohibited file name error when executing the send button. So basically I just need a way to store the filename text.txt without the C: extension so I can specify THAT name as the "remotefilename" which Chilkat will understand. The way I'd really like to do it is to have my send button remove the C: from the existing textbox and just leave the filename there - that would be fine.
I tried to research this and found that the path.Getfilename may be used for this, but I'm not totally sure how i should go about it. Here is the code of the Send button for my FTP Program so far. *By the way, this program works 100% if i just create another textbox, take the filename "test.text" and reference that as the remotefilename.
