I have made a registry entry as follows: HKEY_CLASSES_ROOTMy AppShellOpenCommandAnd gave it the value: "C:Program Filesmyapp.exe" "%1" "%2"I also had a drophandler to for the apphis entry works fine for opening one file that is dragged to my app's icon. The problem is that I can only drag one file at a time into the app. If I try to drag more, it only ees the first file and ignores the others. I use the My.Application.CommandLineArgs array to access the command arguments. For example, My.Application.CommandLineArgs.Item(1) will open the file. If I change the registry entry to:"C:Program Filesmyapp.exe" "%1" "%2" "%3"This will open the first two files, but ignore the rest. If I change the registry entry to "C:Program Filesmyapp.exe" "%1" "%2" "%3" "%4"This will have the same behavior as the previous entry and ignore all but the first two files.
I'm trying to copy multiple files from a directory, put them into an array, then copy just the 30 newest files(I haven't coded the 30 newest loop yet). I added a list box to the following code just to ensure the all the files are storing into the array properly... they are. When it try's to copy, it renames the first file to .log, then tells me that the .log file already exist. How do I get it to copy and keep the source file name in the destination folder Eventually I'll loop this and grab only 30 of the files.
Here's the code I'm playing with: Private Sub transferButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles transferButton.Click
Error is coming Registry Access is not allowed.While Opening a Key.
Code: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click NewDelete("HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun", "Sonia") End Sub
So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME CALLNAME BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
Ok hard to explain this one, it may be the codeproject addin i added recently or its a setting i have changed somewhere but when i'm debugging my app opens up many .cs files, kind of interesting but when i want to step through my code it goes into these files and when it errors it has no reference to where the error actually is. sometimes these files being opened have errors on them which i have had to correct for the code to work.
Has anyone seen this before and what could i do to stop it, i wish to confirm that it is this addon before i remove it (which i will do if it is this addon causing this).
I'm writing a program which gets the time and date from forums which only show "x hours ago" on the main thread list.What I do is get a list of threads, open their print version and fetch the info.I'm currently using a single webbrowser, because there's no control array anymore. This makes the proccess very slow.Is there a way to open all the threads' print versions simultaneously?(BTW, I'm using DOM functions like GetElementsByTag, so I'll need to get the page's "Document" object.)
I am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
i need a way to open a offline registry and read the oem info from it. The registry will be from a a hdd from another pc atached to mine. What im trying to accomplish is open the offline registry and read the model/serial info on it. i am able to read the registry of the booted system but no a offline one.
I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.
I am trying to list all printers (PrintersConnections) under all users (HKEY_USERS)
problem is I dont know the user name keys in advance and need to exclude .DEFAULT and *_CLASSES so first I need to list all key names (%usernamekey%) directly under HKEY_USERS then for all keys that lists lsit all keys under HKEY_USERS\%usernamekey%PrintersConnections
Here is the code I have so far but I get errors about object variable not set, I suspect because of the way I doing the for each and listing the key names and then doing it again
Code: Private Sub DetectPrntrs() Try Dim RemReg As Microsoft.Win32.RegistryKey
I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?
I am trying to delete multiple files (.reg files) by using following code.
Quote:
My.Computer.FileSystem.DeleteFile(Environ("%systemdrive%") & "*.reg")ut its is generating an exception: Argument Exception was Unhandled.Illegal Characters in path.
So i have some source code here what it does is uploads multiple files to ftp in this case files with .jpg extensions the problem im having is how to get the code so that i wont have to use an openfiledialog tool
Imports System.IO Public Class Form1 Dim i As Integer Dim myStream As Stream = Nothing
[Code]...
Im using this code to upload alot of pics onto my ftp server and having to open each file and select all the pics just isnt working. If theres a way to simply grab all the .jpgs in the my pictures folder and upload them that would be a great help
I've been having for the past few hours? What I'm wanting to do is create a program which essentially removes a certain string from the filename in all files. So for example I have:
I have to rename a bunch of folders in different directories. What I would like to do is type in a directory and rename/move files into another directory. I have 4 txt files right know, one for the old file names, one for the new file names, and 2 for the directories.
I planed on importing the txt files into 4 arrays and then using the rename function to change the directory going through a loop.
Problem is I'm very very new to VB and have no idea how to import each line of the txt file into the array.
I got this .dbf file with 80,000+ objects. Using vb.net 2008 I am trying to export the data from the .dbf into a .mdb file. Problem is that when I try to open the mdb file in Access, it says that the file reached the maximum limit of records. I found out that .mdb files could only hold 32,700 + objects in one database.
Is there another way around the maximum number of objects such that I could fit 80,000 object in it? If not, is there a way to, instead split the data from the datagridview into several parts that can be saved into multiple .mdb files?
I'm not sure how to use it, And for some reason I couldn't find it on MSDN, Unless I looked it up wrong, But I am making an MP3 Player, And I'd like to choose a folder that carries multiple MP3 files, And by clicking on it, It will bring the MP3 files into the windows media player component I am using and add the file names into a listbox.
I'm trying to write a program that will take emails that I have saved from outlook as text files and scan it for specific data, and return those strings to a textbox (i will modify it so it outputs the exact way i need it, i just need to grab that info faster than it takes by hand). I dont know how to go about actually grabbing that specific data.

There can be only one grouping (denoted with asterisks, they are separated in the emails like that as well), or 50 and any number in between. I only need the information as shown in the text file example above (sometimes, it is blank or not there - if that's the case just skip and messagebox.show to alert me that it was skipped).
I have a group of buttons all with different labels. I want to have each of these specific buttons open up the same form, but my problem is when I write the code of form1.show it pops open twenty or so different windows. How to I make one button open just one window?
Over the past months I have been working on small windows forms applications and learning vb as i go along. The aim was to pull these altogether into one big application.
I am now at the stage of pulling these together I have created a new project (called MainMenu) and designed all the buttons and interface. I have added my other projects (SISApp, CURApp) to this project. File > Add > Existing Project. I can see these projects in the solution explorer.
Now my problem. How can show Form2 in the SISApp project when I click ButtonX in the MainMenu project.
I dont just want to show Form2, i want all the functionality and the database connection in form2 to also work etc.
Since last 2 days I have been getting a strange problem with my Vb programming (VS2005). Whenever I open any Vb or C# code and press F5 (in order to debug), several windows open at a time like Memory1, Memory2, Memory3, Threads, Processes, Registers, Data sources. And simultaneously the SOLUTION EXPLORER that is present at top-leftmost corner generally goes missing. When I restore that and put my cursor over SOLUTION EXPLORER, the program hangs and a message comes as : "Microsoft Visual Studio has encountered a problem and needs to close".I have attached the screen shots of the problems to this Thread.I tried various ways like restoring my computer to an early date, repairing Windows XP and then uninstalling and reinstalling Visual Studio. But none seem to work.
I am having a serious issue with Visual Studio 2005. Whenever I open any Vb or C# app and press F5(to debug), multiple windows open simultaneously like Memory1, Memory2, Threads, Processes, etc... Also, SOLUTION EXPLORER goes missing from top-leftmost area(where it is present usually). When I put the cursor over SOLUTION EXPLORER (after restoring it), the program hangs and the following message is displayed: "Microsoft Visual Studio has encountered a problem and needs to close".
There is no option to attach something, otherwise I would have attached the screenshots of the problems.
I have 19 .CSV files that hold engineering data in single and multiple Arrays.I would like to loop through the Directory that contains the files and open each file, fill the array and close the file and continue to the next in Alphabetical order.
This code tells me how many files I have now and will update if I add more.
Dim FolderPath As String = IO.Path.Combine(Application.StartupPath, "DATACSV Files") Dim TestFolder As New IO.DirectoryInfo(FolderPath) Dim FileCount As Integer = TestFolder.GetFiles().Count
FileCount give me my number of files but not sure how to continue. I have the code to open and read the file but not how to keep changing the file name for each new file name base on the number of files that exist.
I'm making a flash player and I've been trying to figure this out for months now and have posted several different topics but none of the answers fixed my problem. I already know how to set my program to the default program for flash files on the computer, but I can't actually open files with my program without having my program open and loading it from the open file dialog in my program.
