I'm making a custom control that needs to look like a Text Box but I can't Inherit Directly from text box since I need to add, Change and Override so many things that it would be more practical to just inherit Control and start new.
But now my question is: Is there an easy way to create the basic functionality of a Text Box like drawing the Text Box and handling input ?
E.g The user enters data into txtName, what i then want to do is make a text box with the data entered into txtName
So if the User enters Daniel into txtName, then a txt File is created called "Daniel.txt"
i have created a program to view images in a picturebox, i have created two list box's one for folder names/image areas to group certaint images and the second listbox to list the number of pages contained in the image folder/area. when the user creates a new image area, he or she can name it whatever they want, when they do that i would like to create a folder in the c drive for instance with the same name as the image area, and i would want it to create a .txt file aswell to keep memory of what they have done, so when they come back to it the next day they can just carry on from where they left off.

I think I am supposed to use asmx web services with arrays converted to json? But all the examples I have seen are in C#.
I am attempting to create a class in vb.net from the below JSON example.I am fairly new to JSON, and I am just having trouble figuring out the correct way of doing this. I have looked at numerous examples of how to do this but they are in much simpler formats than the one I am providing below.

I am guessing this is poorly worded, but I am struggling to find a good example of how this would be done. I need to have the class correctly formatted so when I deserialize into the class it works without error.
How to create this JSON array using vb.net array [code]...
View 1 RepliesI am been stuck on this for 3 days now...I have been accessing the twitter api to pull a user_timeline for a list of users and the json that comes back is impossible to work with. I tried to deserialize it using javascriptserializer and get an error:invalid object passed in , ':' or '}'
Now this is frustrating since I expect the json being returned to be error free. Then I tried json.net and split the posts using string.split and tried to convert each post to Jobject or jarray. for Jarray I get
'unexpected end of content while loading jArray

Now I have formatted the code here and not pasted the whole file but it does look like valid json to me and I do not alter anything after receiving the stream from the twitter api. Can someone please point me in the right direction? I really need to get this stuff parsed?

I am accessing the facebook api and using the json.net library (newtonsoft.json.net)I declare a Jobject to parse the content and look for the specific elements and get their values. Everything works fine for the first few but then I get this unexplained nullexception error " (Object reference not set to an instance of an object)Now I took a look at the declaration but cannot see how to change it. Dim jobj as JObject = JObject.Parse(responseData) message = jobj("message").tostring
The error occurs at the last line above.I check to see if message is null and then look for the next desired field as follows
[Code]...
This is one example where "message" does not appear in the first few lines but appears later. So what I do is look for position of message and description and which ever is first go and get that and if I get an error or the fields do not return anything, I try and parse by regex and even that is not working right.
I have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX
<WebMethod(BufferResponse:=True, EnableSession:=False)>
Function Test(aObject as Object) as Object
' object will have been successfully serializaed into a dictionary

So far I have found nothing. I know I can create one using vb Studio, but i'm trying to write a script for SecureCRT that will allow multiple lines of data to be input, then only certain information pulled from that data, run in a command, then the output set to a file. This will then loop and append any further output data to the end of the same file.I've so far got it built to ask for how many times it needs to loop based on how many servers we are checking on, but we are looking to cut the time down to where we can copy the info into the clipboard, paste it into a text box (when prompted for a mutli server check) then run the above paragraph as noted.
