I've been using the process shown here: [url]
For including images in my database, what i would like to do during the import process is capture some of the meta data to store against fields in my database as well.
In this case we will be using iPhone 4s which i believe capture data in EXIF format.
I did a bit of looking around on my own and apart from: [url]
How do I Edit and Save Image EXIF / Metadata / FileInfo without using an external DLL?
Project:I'm building an app for personal use to rename, retag, and organize the apocalyptic quantity of images I host on my personal website. As I have been collecting funny pictures and such for several years, there is no real rhyme or reason to the file naming conventions. Ergo, Image0001.jpg needs to be renamed to a descriptive filename, and the Metadata fields need to be filled in.
The desired process will take an existing jpg, gif, png, tiff or bmp and do the following:
load image into memory
convert bmp files to jpgs if needed (for a smaller file size, mostly)
load image tags into ImageData Structure (see below)

[6] allow editing of fields and renaming of the file
[7] write the changes to the image file
[8] go to next file.
Example:
[1] Load Image0001.jpg. Populate ImageData Structure fields.
[2] Type in Description: "lolcat ceiling cat sends son".
[3] ImageData.FileName changed to "lolcat-ceiling-cat-sends-son.jpg".
[4] ImageData.Name, .Keywords, .Title, .Subject, and .Comments changed to "lolcat ceiling cat sends son".
[5] Save file with new filename and save all new tag fields.
(Later, I will also be using SQL to build a referential database with links to the online copies of these files to allow for searching by keywords, subject, filename, etc, but that's another layer that's much easier than this one. At least to me.)
Problem:So far, several days of research have yielded almost no measurable progress. Information has apparently been inexplicably hidden behind a bunch of unexpected search keywords. Current Code as is:

Basically, Microsoft Freelancer has a "chatbox" and I want to pass skype to and from the chatbox using VB.So if I want to type "Hi everyone" into skype, I would type "/s Hi everyone" and theoretically my VB app catches the message and passes it to skype.I can do that part using windows hooks.

View 1 RepliesI have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:
I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.
Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:
Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.
How do you read the data from a file on the computer? I have an mp3 stored on my root folder and I want the form to read the raw data from it so I can do some encryption etc.

how to read data from a USB Port.

View 8 RepliesI have a datagrid which I have manually added columns to and adding rows at runtime (code I am using below if that helps in anyway). When that row is sellected I wish to get the data from different columns.

Private Sub receive_data(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim aBuffer(255) As Byte
Do While SerialPort1.BytesToRead > 0
[code]....
Basically, what I am trying to do is everytime I receive data from the serial port, I turn that data into an array (aBuffer) and I then call another sub using that info.The problem I'm having is that everytime I receive data, the array only fills up to the first 8 bytes! This isn't a problem when I receive smaller packets of 6 bytes but anything else gets chopped off.
What is really frustrating is that it seems quite fickle. I've read somewhere that this happens because the computer is handling the bytes received faster than they are being put in the buffer?? Not really sure but if I put a couple of breakpoints during debug, sometimes the array fills up correctly... Note the maximum size of any one incoming message would be 255 bytes.
Here's what i've got so far, i've written all of the data that i'm going to put into my config file, however i'm having trouble reading the specific string values that I need from that ini file. The parts of the ini lines I want to get are the values in between the I've tried using streamreader a couple things but i'm having trouble figuring that out. I need to parse each line of the ini file to get that value in between the single quotations, so that I can set the value for my richtextbox background and text color as well as a few other things that i've set up in my notepad including tab spacing and so on. lots of these different values need to be converted from a string value to integers, and boolean values as well. (4 of them, the rest of them don't have to be changed because they are already string values when my application reads them to determine it's application load settings.
EDIT: I just noticed in the preview that this is from the version of the app where I had streamwriter write "______ value=" & Something to a file. lol some of the (')s are still in this version, so please excuse that little part. I had them in, but took them out so that I could trim data to get a value easier, but I want to use (')s hopefully when all is said and done.For example, just to restate what I want - in the ini file it will read [setting name] value='VALUE'I want to be able to "get" the string value of "VALUE" within the ini file between the 2 single quotations '
This is an amateur radio project. I have a TNC (modem) that receives a digital stream (AX.25) from my radio. The TNC decodes the AX.25 frames and translates them to KISS frames (the protocol used between the TNC and the PC, see documentation here: [URL] It sends the data as HEX values.
What I'm looking for on the serial stream is the beginning of a data frame marked by 0xC0 0x00 and ending with 0xC0. Should be easy. Using serialport.readbyte() I should get binary data that I can convert to hex and look for the beginning of a data frame and then convert the subsequent data to ascii, as it will be text from a chat session.
Just to try it out and see the raw data coming from the port, I use teraterm or realterm and capture the data and it's a mix of junk (control frames and what not) and valid text. When I display the same data in a text box in VB I get data that look like this:

View 1 Repliesi have a windows form created using vb.net 2005 that allows users to attach files. When the user clicks the AttachFile button, they browse to select a file they want to attach and then the code places the file they selected into a predetermined location. The primary file type they will be attaching is a windows meta file (.wmf).
The attached file is saved and appears as a hyperlink for the user to open at a later time. When the user clicks to open the file, it is suppose to insert it into Autocad; however, it wasn't doing this.
The problem comes from attaching the file using the StreamWriter for some reason its not working correctly. I verified that this is the issue: When i hardcoded the file path to the original file's location, it opens up just fine when clicking the hyperlink. When I compare file size from the original to the one attached, I see that the original is 12Kb and the one I attached is 19Kb.
Here's my code to attach the file: I'm thinking perhaps it has something to do with this line? sReadFile = sr.ReadToEnd() but I'm just not sure. I tried changing this line to sr.Read but that doesn't work either.
