Re: String literal in multiple lines

21-Apr-07 23:51

What made you think that would work ? Does it work in VB ?

string s = "switch(expr){" +
" case IR" +
" whatever"

You can also use @ in C#. when you do, there are no escaped characters and double quote is a quote.

"to do a quote, you do \", and it escapes to a quote"

becomes

@"to do a quote, you do "", and it becomes a quote"

this complier error is becoz of the \ that u added in the end of each line,
use following syntax

switch (expr)
{
case "IR(\"xxx\")+
sql('sele tasudok from dok x +
where doktyyp+str(dokumnr,7)= \"G\"+
str(dok.krdokumnr,7) ','')":

Hope this helps U.

I think we cannot call the base class constructor in the derived class constructor.
But we can do like this.

class derivedClass:baseClass
{
public derivedClass():base(arguments)
{
}
}

First, i am so sorry,i can't explain the problem very clearly. Let me descript it by an example.
eg, if you click msn shortcut, the processes is liks this: double click MSN's Shortcut - start MSN application. Now there is an application coding by me, in it i new a process, the process.startinfo = "MSN.exe",...then process.start(). That means that, i want to make the doule click the MSN Shortcut's processes become this: double click MSN Shortcut - start my application - start MSN application by the process.start() which Statemented in my application. And there are an other problem, if the user chanage the shortcut "MSN" to other name, like "MyMSN", is there any side affect? if yes ,how can i get the correct information?
If any one have the solution, please give me more info. Thank you very much! Big Grin | :-D

I have no idea what you're saying. If you want to start your own app instead of MSN, you need to change the shortcut to point to your app.

I am very sorry to my poor English.
But how to change the shortcut to point to my app?
Thx Smile | :)

yes,it is very smart, but i can not belive that the cooperater can accept this way. And there still have some problems,first if the user not use the shortcut,she or he clicks the exe direcly, what should i do? second, if the user doesn't want to use my app one day, she or he may delete my app or uninstall it, in those case, i must reset the right path for the user.
Thanks for your Support. Hope you give me more good idea~ Big Grin | :-D

Why does the user have to start the MSN shortcuts? Why not just supply the shortcut to your app, if the user want to use it!, and then your app launches and starts MSN? That way, the user has a choice whether or not to have your app in the way of using MSN.

I believe the core point is that he wants to hijack MSN, no matter what you click. Sounds malicious to me ( at a guess, he wants to intercept what is typed and log it )

I figured the same thing. That's why my answer kind of stears clear of modifying the exsting shortcuts.

:->
First, I must declare one thing, MSN is just a example for describing the case, not really.
Maybe Graus have got my meaning. About your suggestion, supply the shortcut to my app, then the user has a choice,it is a good way, but i don't think the collaborator can accept this concept. He is stronger than me, so i am afraid ... Poke tongue | ;-P

, just a joke.
Maybe there is a mistake, Can not start my app first ,then capture the message. It is should be this, No MSN start, No my app,but MSN's application start by my app.

When we use it from a desktop computer in the network to print , it works fine but when we want to use it from a pocket pc program ,it throws an exception and says that the specifeid path is not valid.
What should we do?
Thanks a lot

Noone is going to do your homework for you.

You have the specification for the homework assignment, now you only have to write the code for it. If you have any specific problems you are welcome to ask about them, but remember that you should clearly state that it's a homework assignment that you want assistance with, so that anyone helping you can give the proper guidance. Assume that you teacher also knows what internet is...

I'll do it. It will cost you $20. When your next assignment comes, you won't know how to do it, because you didn't do this one. So, my price will double, and continue to double for each assignment. Then, you will fail your exam, because you still won't have learned anything, and you will drop out.

So, either drop out now, or do your own homework. No point putting it off.

Now that's a hell of an idea ... double the price for every homework assignment. Well played my friend. Well played.
