I can think of the following tricks:
Read only wrapper - like ReadOnlyCollection. The friend keeps the pointer to the modifiable object, while everyone else can access only the wrapper.Write delegate - the friend gives the constructor of the object a reference to a delegate as one of the parameters, the constructor fills it with an address to a private method that can be used to modify the object.Reflection - obviously a bad idea. Included for completeness.Multiple assemblies - put your friends together in a separate assembly and set your modifier methods internal.Expose the modifiable object, but add comments to modifier methods "This is an infrastructure method - don't call it!"Nested classes.[code]...

View 2 RepliesWe have two systems, one is created in VB.Net 2003 and the other is created in VB6. Both systems are client/server desktop application system. There is a requirement that we need to send and response data to each systems. The data will come as result of process of each system and then transfer it to the other system. These is formatted in a message format. Is it likely to become socket programming? how can I send and response data between servers?
View 1 RepliesI'm supposed to design this program in ConsoleApplication about Phone Numbers:
You are writing a program and you need to store telephone numbers. You'd like to be user-friendly, and let the users enter their telephone number in whatever format they like with parentheses and dashes, so long as they enter 10 digits. Assume that they won't enter any other characters. The user will only enter ( ) - spaces and numbers.So, these would all be valid inputs

View 2 RepliesOkay, that's not a big deal... I'll implement FileStreams and read bytes performing operations on them. The problem is that if I do this, the program will hang until the hashes have all been calculated. I want the program to show the hashes calculated so far and a progress bar. I know I need to implement this using threads and interrupts, but how, P.S. Any example code, simply for showing the progress of any operation, and involving a thread,

I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.
View 2 RepliesI seem to have reached a limit on the size of the form. I cannot make the form longer and I need to add more fields. Is there a limit on how many fields can be included in a form?

View 1 RepliesNeed to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

i want to users to be able to vote for their favourite soft drink. They will input the names of the soft drinks through the use of an inputbox, the names input are stored in an array. what i would like to do is count the votes given to each soft drink. How would this be done, please provide example code if possible.
p.s. i tried using a listbox and failed.Well during the set up of the program they will input the names of all soft drinks up for voting, and then all the soft drinks input wll be displayed in a list when the voting take place.
I'm trying to do here is get VB to hold a key down until I tell it to stop. Perhaps I'm missing something but I don't understand why this isn't working. This code can hold down shift and so on for as long as I want it too but absolutely refuses to hold down what i need it too (any letter key or numpad key)[code]
View 1 RepliesWell i've been trying to make something run with a lot less code(and faster) but it seems with SendKeys some things are getting lost(or discarded) by the program, its only the arrow keys as I try & make it complete a pre-defined maze to see how fast it can be completed.
If I use SendKeys("RIGHT 8") for example the maze usually only moves a few times, sometimes maybe only 1.
Also I looked up how to hold a key down/simulate it but it's not working for the arrow keys(untested on other keys).
The only way i've made it work is delays, decently delayed like 200ms & it's a huge maze but if i hold a key manually I can go much faster yet sendkeys method can't go that fast using individual presses this is why I want to simulate a holding down action.
---it must be working xample code I can make it work for my purpose if it works like on button click, etc....but I tried copying full (supposedly working) codes before & they never worked for me/my key, xample cause i've looked & tried hard(with only failing results).
MORE INFO:Also I tried SendKeys.SendWait() which is meant to wait for keystrokes to be processed & that didn't help either so my best guess is the keystrokes are processed but discarded(like a movement delay code that doesn't queue movements but rather ignores extra movements)

Damned. Is there a managed code somewhere in vb.net where mortals can simulate key presses?
Is there an e-book or book somewhere about it?
Is a way to get the same in VB.net?I've tryed with DrawImage but it doesn't work.
