I want to save a bitmap object to file, but I want to make sure the file path is writeable first. The user should have write permissions to the folder and it should not be a location on a CD drive.Right now, it gives a "A generic error occurred in GDI+", which is not too helpful. I'd rather tell the user that the selected save location is not writeable.
View 6 RepliesI have created a folder and a sub folder within it and trying to check if the folder exists or not in the registry editor.This is how I have Created:
Dim kstrRegSubKeyName As String = "CompanyName\SoftwareName"
Dim oReg As Microsoft.Win32.RegistryKey
oReg = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software", True)[code]....
Now I need to check if that CompanyName Folder is deleted or not and display a message.
I want to create a simple program that runs in the background that every few minutes checks to see if any additions to the "startup folders and or the registry entries that run programs. How do I make the value of these folders or registry entries variables?

View 3 RepliesI've got an app where the user uploads an image and the app resizes the image three different ways based on different variables. They all use the same image. I can't check to see if it's done using the image so I wondered if there was a way to check to see if the file is writable. A small loop that exits once it becomes writable (or "deleteable"). Working out of VB.NET.

have just started vb .net and im working with the 2005 edition, but i would now like to make a program that i can use at home that will alter files names,Bassically where i rip cd's to put them onto my mp3 player they are always given a name starting with 01. etc, what i would like is a small bit of code that uses a while or for loop to go through every file in the folder and remove the first three characters.
View 4 RepliesI am making a file program that will store information that a user can not edit without using my file system. The only two ways I can see how to do this is to either create an invisible folder to hold the files, or make my own extension. I think it would be easier to create an invisible folder through VB if possible. Can anyone point me in the right direction.

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
how I could check if a certain file is in text or binary format?I'm using VB.Net 2008 Express.

View 3 RepliesI have a folder that can (hundreds currently) but upwards of 10's of thousands of files. I have a program that gets all file names, and sorts them based upon set criteria and displays them in a treeview. My issue is right now a few hundred files moves fairly quickly when getting files name (path.getfiles), sorting, and returning sorted list for further search and display. My concern is when the number of files starts to increase, alot of these functions will take exponentially longer to perform. Especially my organizing function.
Because my files are part numbers <PartNum><Rev><SubRev><ManuNum>.<extension> I first sort out all different Part numbers first making the list manageable (maximum of a few thousand). Then as you choose a part number to work with, it retrieves all files associated with that part number (maximum of a few hundred).
My concern is everytime I need to look for a file in anyone of those steps, I have to import all file names, search and return correct file path, and Im sure this will become slow as the number of files increase. I dont mind having it do it once then update the list as needed. So I was thinking import and sort all file names at load, and check every so often for and files that might have been modified recently and just update it's entry in the sorted list. But this means my program has to stop, and check all files for changed "modified" time, which too will be slow-ish.

View 5 RepliesI'm doing a uni assignment and my application has to go to a specific folder and locate a file for data.The folder has 300+ files in it with a specific format for the naming of the files ie. the program goes to the folder looking for one specific file that has been derived from a different function and user input in the form.The program works fine when the file that it is searching for is there, but I keep getting a FileNotFoundException whenever the file that it's looking for is not there.I don't want the application to throw an exception every time the file doesn't exist because the program needs to return back to the loop to see if the next file is there or not.And so the loop continues until it's found all data and loaded it all into an array.How can I do a check of the folder to search for the file, and if it's not there, go to the next step without throwing an exception?

Currently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.
View 1 RepliesI 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.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
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?
