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?
Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>" Dim patternend As String = "</FileName>" Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)
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 don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog dlg.InitialDirectory = m_sReportFolder dlg.FileName = sProjectName & ".docx"[code]......
I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
I encountered the error:The process cannot access the file <full file path> because it is being used by another process.during System.IO.File.Delete(filename)I have opened the file using:pctPhoto.Image = Image.FromFile(filename)before I delete the file.
In my vb.net winform application, I am moving the file (ex: sample.xls from one folder to another. If file already exists with the same name, the new file name should be incremented (ex:sample(1).xls). How can i acheive this?
I get the common error: " 'File Name' is currently being used by another process..."
My problem is that I have two forms. If the file doesn't exist in the one then it creates the file and opens up the other form, if the file exists it doesn't do anything, however, in the other form that it opens up I have it "attempting" to write text via StreamWriter. But my problem occurs when the StreamWriter tries to open the file for writing, that is when the program tells me that the file is currently being used by the other process.
In my first form I close the form via Form.Close and all I am using to create the file is System.IO.File.Create. Now I know that the System.IO.File.Create is causing the error because I have this process checking the very first thing on the program load. I am trying to find a work around the System.IO.File.Create but no luck here... I am trying to create a .txt ... lets say test.txt .
i want to Encrpt a file . i write the code.System.IO.File.Encrypt(FileName). But file is not Encrypt. it just change the color. but when i open it in note pad. it open currectly. how i use file.Encrypt function
I need to aquire the full path and filename of a file to add them to a database. I'm currently using OpenFileDialog and in debug it shows that when I select a file, the Filename property is the files full path with the filename. What is the best practice for extracting the full path from FileName?
I have an application, that I have integrated into Windows Shell, for this example I will use Notepad. You can right-click a file on the desktop and select 'Edit with Notepad', this launches(if I am not mistaken 'NotePad %1') notepad, and opens the file right away for editing.For my application I need this to get the file name, so basically I would right click on my application, and it will run and have the filename for me to use inside the application.
I'm looking for a way to get the name of the file that's currently selected in a Windows Explorer window, desktop included, without having to use a FileDialog or to copy the path to the clipboard (GetFileDropList). I've been looking into the System.IO.Path.GetFileName() an many more methods like that, but I haven't found anything that does the trick.
I want to create VB.NET code that will change the filename of selected image files that are already stored on my ISP's web server. I know how to do this by reading the image into memory and then saving it as a new file. However, I would prefer not to regenerate the image. I just want to change the filename. Is this possible?
I am attempting to use the VB.Net FileSystemWatcher class to watch a folder for the creation of Excel files.I do get a response when a .xls file is created in the folder, but am having a problem with the below code:
We have a network folder that is the landing place for csv files processed by different servers. We alter the extension of the csv files to match the server that processed the file; for instance a file with the name FooBar that was process by Server1 would land in the network share with the name FooBar.Server_1.
The information I have available to to me is file name: FooBar and the path to the share. I am not guaranteed the extension as there are multiple servers sending csv files to the network share. I am guaranteed that there will only be one FooBar file in the share.
Is there a method in .net 2.0 that can be used to get the extension of the csv armed only with the path and filename? Or do I need to craft my own?
I have a sorted array of files saved in the following format of filenames:
XXX XXX_XX XXX_XX_XX
I want to insert a new file (with a unique filename) between two given filenames (which could be in any of the 3 formats above).
For eg., a new file between 401 and 403 could be inserted with name 402 and a new file between 401_01 and 401_02 could be inserted with name 401_01_01. etc
The idea is to conform to the sorted list. Is there a way I could generate filenames for the files to be inserted, given the two filenames between which it needs to be inserted?

I would like to parse a string to extract embedded parameters. [code]...
I split on the colon, then check each entry for the string "image", when found, I then extract the next entry.
I would like to use the ParseQueryString()method which works fine with equal signs and no spaces. Does anyone know if this method can work with other delimiters and spaces?
