View 9 RepliesOK so in this hex editor I have, Hex Workshop, when I search for a 32 bit float i type in (lets just say) 1. It then spits it back at me in a 32 bit float, but also as hex.
the 32 bit float for 1 = 3F80 0000
I really cant grasp this idea, let alone put it into my program.
able to convert an integer to a float then to that sort of hex.
I am receiving a data stream which contains 4 bytes of data which need to be converted to a 32-bit float (IEEE 754). This was easy to do in C as I created a union with a 4-byte array and a 32-bit float. Job done. However I have no idea how to accomplish this in VB (pls note I do not code in VB).

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.
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.

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.
I am working in windows application, I have one field in sql server which has data type decimal(15,10). When I enter data from application like "123456789012345". It should be convert it in 12345.678901234 when press tab on text box.
View 4 RepliesMy program works through each cell in a raster bitmap loooking at the r g b values. Actually I'm just working with greyscale so r = g = b. I use the get pixel method to return the 8 bit value of each pixel (0 - 255). However I'm now working with a single channel 32 bit float bitmap. I can't load it into VB. I tried Dim myBitmap As New Bitmap(OpenFileDialog1.FileName) but this fails with an unspecified error when trying to open a 32 bit tiff.
The question is: which graphics format will allow me to load a 32bit bitmap into VB, and if I succeed will the getpixel method return 32bit float results for the greyscale level for each pixel?
