Using StreamWriter To Attach Window Meta File?
Mar 27, 2012
i 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.

Ive come up with an issue in a program im making, hoping someone might have a clue. Basically I want to enable meta gaming into a ORPG I play. Obtaining all the meta gaming was easy enougth to do, now I have to add it into the game (Microsoft Freelancer) But ive run into a problem.I don't have a clue how. 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. But when skype chats back, How to post into the game?Ive run a sniffer, But I get data that I have no Idea what it is.0000 80 06 01 00 CD DE 00 00 93 F5 06 00 I do know the ip im sending to and the port, If that helps, And the rest of the program functions, just sending and receiving the chat data is beyond me atm.

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)

[3] load image tags into ImageData Structure (see below)
[4] load file data into ImageData Structure (where needed)
[5] display image and tags for user to edit (In a Picture Box and several Text Boxes)
[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:

Imports System.IO.Path

I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

I would like some code that would make a Vb.net Form EXACTLY like it should be a control (label) of an external window.This means that when the external window jumps in foreground the Form must be visible on the external window, but WITHOUT to take out it focus.If a third window covers partially the window and the Form, the form must be displayed only in it the visible part: in short, like it should be a control of the external window.
I can't use ShowWindow because also if I use the _NOACTIVATE constant, the external window loses the focus, and if I click on the external window my form disappears until the timer routine put it again on the top: no good.
I can't use TopMost because if a third window covers partially or totally the Form, it don't hides partially or totally the form itself: is the form that hides part of the third window:

Basically I have to create an application which is a quiz. According to the users score it will then determine what level of skill they have.I know i could do it really easily, by having a number of labels on the form which hold the questions. Then underneath have radiobuttons with possible answers. From this then use an IF statement to add a digit into an invisble label which can tally a score of correct answers. Assign each invisible label a variable which then can be summed in another label, from the score then use a SELECT CASE statement to let the user know what level they are at.But I know that this would mean alot of code and objects on the form. I have read that it would be more efficent to use an XML or TXT document to populate a label and radio buttons, this way it would also be easier to change questions and randomise them.The only problem is that i dont understand how to attach the XML or TXT file to the form so that it does the population of labels & radiobuttons.

Dim fs As New FileStream("C:est.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)Dim b As New StreamWriter(fs)
b.WriteLine("hellothere") : b.Close()
b.close is necessary to save changes to the file, but then, fs will be closed, too. is there any method that does the same thing but doesn't close fs, like "b.save"???

VB 2005 now offers different methods to write/read a file, such as the File.WriteAllText, the My.Computer.FileSystem.WriteAllText and the StreamWriter.Can anybody explain when is it better to use which method, which one is more efficient in term of memory/processor use and performance time?

I have no experience on this matter, so I do not expect anyone to explain in details how this is done, just point me in the right direction, maybe tell me what the correct name for this is. I'm sure it is pretty commonly in use.
I think the best way to explain this, is through my exact need. So, I have a button on my website that should cause the user to download an exe file. The exe file pretty much gathers a few informations from the users PC, and post them to my data-base through a web-service. Now my problem is, these informations should be assigned to the user who downloaded the exe file's row in the DataBase.All this would be solved by assigning a single Integer value(the users ID) to this exe file on the download request, and then a way for the exe file to also get this value assigned to it, but how do I do that?
My language is asp.net for my website, and the exe file is written in vb.net.I know I could fake this by making the exe file show a login-form and get the user-id this way, but I really like the application run without the user noticing to much.

This may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.
[code]....
Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.
