View 4 RepliesI've been stuck on this for 3 days now.I have a TiffBitmapDecoder accessing a file and generating a BitmapSource from one of the frames in the file. If I try and modify the file after that e.g. insert new frame or even delete file, I'm informed that the file cannot be accessed as another process is accessing the file.How do I either a) Get the TiffBitmapDecoder to release the file or B) force all processes that have access to a file to release?Note: I'm using WPF and the TiffBitmapDecoder does not have standard fileStream methods like close, dispose or flush.

I Am a new developer in VS 2008. I am writing a small program that reads an XML file. Here is a snipet of code.
filename =
"XMLPolicyList.xml"
Dim DR As XmlTextReader = Nothing
[code]....
My understaning is that the system looks for the file in the bin/debug folder, so that is where I put it. But when executing this program. I always get a FileNotFoundException. The file name displayed is (filename). If I hard code the entire directory name and file name I get the same error and the file name is displayed with the same slash in front of it. For instance I put the file on the C drive and the error displayed C:(filename).I don't have the problem in older versions of Visual Studio. The same program runs fine in VS 2003. I'm thinking that there must be some sort of setting within VS 2008, but I have been unable to find it.
It's all fine, accessing files and directories by using a dynamic link library (DLL), but is it possible to do online?Suppose I want to parse a file, which would normally be simple in visual basic; is it possible to call functions from a DLL using a server-side language, say PHP?

The issue is that if there is an existing file and the operator loads it into the 2nd picturebox, the operator isn't able to overwrite this image file from whatever is in the 1st picturebox.

View 2 RepliesI have an external project (DLL) that I have referenced in my project. One of the requirements of using that DLL is to include an XML file in the same directory as the DLL. Now I know in a production environment I could just add that DLL to the GAC and place the XML file in that same folder. However, that doesn't help me when I'm trying to debug it. I have tried including it into the BIN directory but it never gets moved to the Temp directory when compiled.

I was wondering if there is any way to manipulate layers of a psd from within a VB program. I would Ideally like to inserts just the psd file in and then once a command is clicked turn one of the layers on or off.
I know I can accomplish this inserting a jpg/gif for each layer and have that image be turned on or off by a button click, but I figured using the psd would save room and if something needs to be aligned differently I can just make a change in photoshop. Opposed to trying to realign the coordinates in VB

View 9 Replies(First off all hi to everyone my first post!) Ok, i have two programs one program writes to a text file on a consistent basis, while the second program is opening this text file on a consistent basis for reading.. Sometimes the programs are accessing the file at the same time and the user keeps getting this error : this process cannot access the file because its already in use..
Is there any class, in system.io that i can use to modify the settings of this text file so both programs can access it at the same time?
For a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.
After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.
I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.

I was writing a small test to verify loading and editing a bmp file with a process and MS Paint. If I load the file image into a picturebox before I run the process MS Paint reports a Sharing violation on the file during save. If I Leave the Picturebox empty MS paint allows the file to be saved.
Below is my snippet. I assumed setting the picturebox image to something else would fix the problem. I does not. Looks like something is still holding its finger on the file.
Code:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Remark the line below out and there is no violation.
PictureBox1.Image = Image.FromFile("C:Tom.bmp")

I need to access a file path, but a part of the path is different on each PC. Mozilla creates a random profile name for each PC it is installed on. I can get most of the path through environment variables. I need to access the files inside of the default profile, but can't since I'm not sure how to access it.
Here's an example of the file path:
'C:Users\%USERPROFILE%AppDataRoamingMozillaFirefoxProfilesxxxxxxxx.default'
The only thing that stays the same with the profile name, is the '.default' part.

View 1 RepliesI have written a program in VB 2010 that dumps documentation info into an Excel file. Basically, the Excel file is a log file that keeps track of revisions for design drawings at an engineering firm.
There are approximately 20 people that have access to this program. However, I've run into issues where multiple users may be using the program and trying to send info to the Excel file at the same time. The Excel file is set to read only. My program opens the file with write access, and dumps the info into the appropriate cells, then closes the file. If one person is in the process of using the program, it causes an error with another persons system if they try to use it at the same time.
In some cases, it causes my program to crash, and it leaves the Excel file open on someones system.
Typically, my program would only have the Excel file open for a couple seconds. So, the issues mentioned above are rare, but they do happen.
I'm looking for ideas to prevent this issue from occuring.
