Let's say I have 2 applications, app1 and app2. If app1 were to use SendMessage to set the text of a control in app2, is it possible for app2 to get the HWND of app1?
View 5 RepliesI want 2 forms the main form which is form1.vb and the second form which is form2.vb to share the same value:
Dim Name As String="App1" so i can use it by simple doing that:
[Form1.vb]
Public Class Form1
[Code].....
Or it could be better if i didnt have to add a reference to the main form the string Name should be already declared in the second form so i could use just:
Textbox1.Text = Name
I have a RichText area, and wanted to create a button, that will take whats in the RichText area, and come up with the prompt for the user to save somewhere on the machine..
View 1 RepliesI need to parse a Unix text file so, I am using System.Net.WebClient to ftp into a Unix server then using the .DownloadFile() method to get the text file, but its coming in with the Unix end line ""; so is there a way to convert that to windows format while doing the DownloadFile method? I do re-read it after and fix it, I am just looking for a better way.
Or is there an alternate such as instead of a DownloadFile, and the two other steps above can I just read it into an array right off the Unix server?? If so then what method would I use?
Possible Duplicate: What's the purpose of the Tuple(T1)/Singleton in .net?
Trying to mimic a Tuple as implemented in .Net 4 (For .Net 3) I just realized there is a Tuple(Of T)? This was quite a surprize!
Tuple<string> result = new Tuple<string>("Data");
Instead of this
return "Data";
Isn't the whole point of a tuple that its a container for "loosely related data that isnt cohesive enough to make another class"?
I have a question, i have worked in several languages in my life (including several versions of basic) but i wonder whether in .NET using a variable or equation in a loop is a lot slower than not using one? Take the following identical loops
Dim test(999) As Integer
For count As Integer = 0 to 999
test(count) = count
Next
[Code]...
Now the 2nd case is good because it is easier to adjust the code should the array size need to change yet my background tells me the 1st case is the one in terms of performance, test.Length - 1 is calculated each time the loop runs. a loop of the 2nd kind for example has a massive effect on java as well as VBscript or javascript.So heres the question, would test.Length - 1 be calculated each time the loop ran, or just the first time?

I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.
I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
