I'm trying to use a combo box to change the image in a picture box to one that's stored in an external folder. The plan is to, in code, take the part of the file's location that will be constant and concatenate the file name to the end. The file name is stored in a database.

These are two code blocks from the two programs I have wrote. The first is the server program that receives a connection and writes the file to disk. The second is the Client program that sends the file to the server to be written to disk.As it is - it hangs. I did once get it to write to the disk - but the file was twice the size of the original. what objects to use for transferring a file over a TCP IP network connection with TCPClient and TCPListener.
The code for this is:
'IMAGE HANDLING
Dim bytes() As Byte = DS.Tables("Location").Rows(0).Item(4)
Dim ProductImage As Image = Image.FromStream(New System.IO.MemoryStream(bytes))
pic_ProductImageDisplay.Image = ProductImage
pic_ProductImageDisplay.Load()
The error occurs line 3 stating "ArgumentException was unhandled: Parameter is not valid."
1. Since the plate number will be stored directly into the database after being converted from the image. However, due to the conversion process of the image into text takes few seconds, it is not able to be stored into the database... May i know is there any code that can solve it? Maybe can delay the process of storing the plate number?
2. Why during running my VB, when i click on the listbox, sometimes it will immediately pop up a dialog box to ask for video source, but sometimes not? How can i solve it?

How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...

I am new to ADO.Net and I mistakenly using the dataset as how we use recordsets in ADO., I know that it is possible to create a Datatable which will only reside in the memory and hold data. What I need to create is like this.
1. Create Datatable.
2. Fill it with sample data at least 3 lines.
3. Transfer the data from datatable to database (access,sqlsrvr etc).
I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.

View 2 RepliesNeed to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

i dont have these parameters. i only have 1 field in sql server table that says Img and has image datatype. how do i use this code to get my image in db using this insert statement?insert into table1 (img) values (???)
I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
