I need to take a picture, test.jpg and read it in and convert it to a string.
The string is going to be sent via email attactment where i need it to work as a .jpg when i download the file attachment.
I can only build the file attachment using a String so i will need to convert the picture into a string, without losing any of the data bytes.
Currently, I'm using the following code to pull info from the management class.
[code]...
I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.

View 5 RepliesI'm trying to convert an ASCII String to hex for VB 2008. So far I have this :
Code:
Function asc2hex(ByVal StrName As String) As String
Dim loopCount As Integer, strHold As String
For loopCount = 1 To Len(StrName)
strHold = strHold & Hex(Asc(Mid(StrName, loopCount, 1)))
Next loopCount
asc2hex = MsgBox(strHold)
End Function
However, It is not reporting all the bytes that it should be. For example: This is the correct format.

Is there a way to convert a string into a linq query? Searching for those words brings up tons of stuff unrelated to what I'm trying to do..For instance, this works, of course...
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apple" Select item)
But somehow I want to do this:
Dim strQuery = "From item in htMyTable.values where item(0) = " & CHR(34) & "Apples" & CHR(34) & " Select item"
Dim lstMyQuery = (Somehow run/convert strQuery as a query)
The reason is strQuery will be different each time depending on what the user has selected earlier in the program.R if lstMyQuery is already a collection, is there a way to add to it?
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apples" Select item)
(this obviously doesn't work, but it's basically what I want to do...)
lstMyQuery.Add(From item in htMyTable.values where item(0) = "Oranges" Select item)

Background Information:
Table: Customer
Fields: CustomerID, Title, Forename, surname, street, town, country, postal code, home phone, mobile phone, work phone, email.
All the data types in this are Strings with the exception of CustomerID.
Table: Country
Fields: CountryID, Country
CountryID = Integer, Country = String
There is a relationship between country.country and customer.country. I have made country a combo box with the contents of country inside it. This problem is resolved if I remove country as an input - but I need it in!
Been a while since I last posted here. I'm busy on a new project and I need to convert a string which represents a IP range (like this: 10.0.0.0-10.0.0.254), to two Base64 strings which represents the first and second IP adress in this range definition. Like this: (start IP: CgAAAA== End IP: CgAA/g==)I've got it to work, but it such an ugly code, and I know it can be done with 2, or at max 4 lines code. But I'm not so handy with the Base64 string conversion jet. So this is where I ask for help from you guys!
Here's what I got (in goes: Apf.Iprange = "10.0.0.0-10.0.0.254")
Dim StartIp As String = Apf.IPRange.Split("-")(0)
Dim EndIp As String = Apf.IPRange.Split("-")(1)
Dim StartNumbers() As String = StartIp.Split(".")

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

View 5 RepliesI'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.
