How To Get String From Address Specified By Long Type
Oct 13, 2010
In vba, There is an address held by a long type which points to a null-terminated string, but I can't find a way to get the string from this address:
long str_address = ...
string str = ?
vb Dim s As String = strContents '<a global variable) Dim currentPos As Int64 = 0 Dim endPos As Int64 = strContents.Length - 1 '// A dictionary, used to count the frequencies Dim characterCounter As New Dictionary(Of [String], Int64)() While currentPos <> endPos '//
[CODE]...
Gives this error: Value of type 'System.Collections.Generic.KeyValuePair(Of String, Long)' cannot be converted to 'System.Collections.DictionaryEntry'.
I am writing the dim statement to check the url and the textbox1.text to check the full url but its not valid.
Here its the code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Response As Net.WebResponse = Nothing Dim WebReq As Net.HttpWebRequest = Net.HttpWebRequest.Create("http://testsite.com/getInfo.asp?user=" And TextBox1.Text) Response = WebReq.GetResponse
I have a small app that lists user profiles and drives in ComboBoxes and check boxes to select which files to copy. Whenever I select any drive from the combobox I get the error "Conversion from string "" to type long is not valid" I've tried three different methods I've found to display the drives in the box and all get the same error. I planned on having the app create a folder on the root of the drive selected.
I saw something really strange today, that I have not seen before.I saw a variable declared as:Dim a as Long? I am obviously familiar with the Long datatype but what is Long?
I keep getting an over flow.I have two longs. The first is set to 16552800. I can add 32760 to it no problem. However I get an overflow error when I add 32820 to is.
All of the columns populate correctly except for the Long column. It returns a null for all rows. I have tested the SQL statement in Toad and it works perfectly. how to get an Oracle Long data type to populate in a gridview? This is driving me nuts
What data type could I use in my access database that can hold very long texts. By default, each cell in Access tables can only contain up to 255 characters. Is there any way to extend this to any length I want?
I'm trying to find a way to trick the compiler into exposing lines of code where the default "ToString" method of Integers, Longs, Doubles, DateTimes, etc. is being used. These are lines of code that must be reviewd for culture specifics. FxCop does not expose these areas when .ToString is not used explicity in the code.Putting a class in with something like the following freaks it out
Namespace system Public Class Int32 Public Overrides Function ToSt
I have a very long string. I need to parse this string so I can get information out of it. I know what each segment starts with and ends with. The length of the information will vary. I don't know what the easiest way of parsing this string.
Example data will be
ST*997*232898~AK1*HC*8888*~NM1*2*TESTING........
So i will want to get everything from ST to AK1then AK1 to NM1 and so on and so on.
I am working in VB.Net 2010 framework 2.0.I am setting a big string to tooltip object. In this case tooltip is not appearing. If the string is short (say of 10 lines), tooptip is appearing properly.The following is the code:[code]....
If the "PanelText" is too long (say 50 lines), it does not appear. Sometimes it shows an empty tooltip.

I have an address in the type 'array of bytes' (example): 81 ?? ?? 02 53 02 d0 27 To mess with it in visual basic, I use the format in Hex: &H81 &H02 &H53 .....
I do not know what 'put' in relation to the 'question marks' I've tried: &H?? &H_ &H00
I have a client application that connects to a WCF service, i get the file size from the server as a long value then i convert it at the client to a string so it appears like ex:52.21 MB the application gets too many files sizes every time user changes the directory pathso the question is :should i convert the values to a string format from WCF service app then return it to the client as a string format or should i just return the size as a long value and let the client to convert it to a string format in other way which value take more bytes in the memory:
I have a text file with names that have spaces and commas. For some reason when I read the file it gives me this error. Code is below. Also, I am reading the file into a combobox.
I have the following code: Dim ipAdd As IPAddress = Dns.GetHostEntry(strHostname).AddressList(0) Dim strIP As String = ipAdd.ToString() When I convert to String instead of an IPv4 address like 192.168.1.0 or similar I get the IPv6 version: fd80::5dbe:5d89:e51b:d313 address. Is there a way I can return the IPv4 address from IPAddress type?
look at this code and see how i can speed it up? Its calling a sub to count commas in long string.Calling part 'Sort the incomming messages Dim count_Coma As Integer = CountCharacter(_InMessToAction, ","c)
The sub. This takes about 0.7 of a second to count 20 commas in string _InMessToAction. Was hoping to get it down to 0.1... if at all possible.
Ive been searching the Stackoverflow but couldnt find the exact thread that my problem is this, i want to be able to find and take out any occurances of 8 digits wihtin a string.
Dim SetOfMatches As MatchCollection Dim MyRegex As New Regex("A^d{8}$A") Dim TestString As String = "testing 12345678 testing" myMatches = myRegex.Matches(TestString) For each Row as Match in myMatches console.writeline(row.value) Next
this doesnt not generate any hits. but i want to find the 8 digit occurance in the middle of the string.
I am trying to split a long string of data into an array:
[Code]....
Ive tried a few ways to write out the regex, but to no avail. Also, sometimes responseFromServer2 contains newlines, and sometimes it does not, depending on the response I get from the server...
