Hi there:
As you know we can compile a C Sharp program at DOS prompt like
csc MyProgram.cs
Where MyProgram.cs is the source code file.
Now i want to perform the same compilation through another C Sharp Program. Like i made a program named ShellExecution, which tries to compile another C Sharp Source Code File called "First.cs" lying in my c directory. The program runs fine without any exceptions; it opens the dos window and runs csc, but nothing happens and seems like the file name "First.cs" is not being passed to the csc.exe as a parameter. I have used the following code for executing the compilation process:
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\CSC.exe";
process.StartInfo.Arguments = "C:\\First.cs";
process.StartInfo.UseShellExecute = true;
process.StartInfo.RedirectStandardOutput = false;
process.StartInfo.CreateNoWindow = false;
process.Start();
process.WaitForExit();
Please help me out!!!!

Check out the CSharpCodeProvider. It can compile from a CodeDom model, from files, or from strings.

i'm working with MenuItem that i attached to a notifyIconTray... i want 2 add to on of the Menuitem meber new members "on the fly" from combobox, so when i add 2 combobox, i want it 2 be added to the member in the menuitem.the problem is .. that it works only once,,, after i maximize and minimize it back, it wont show me the other members of the Member of the menuitem....
any ideas y it happens ?
it looks like that:
private void Form1_Resize(object sender, System.EventArgs e)
{
if (FormWindowState.Minimized == WindowState)
{
menuItemEntireCat.MenuItems.Clear();
MenuItem[] CatMenuItems= new MenuItem[catcombobox2.Items.Count];
for(int i=0;i

It seems like you have some error here :
vedmack wrote: MenuItem[] CatMenuItems= new MenuItem[catcombobox2.Items.Count];
for(int i=0;i{
CatMenuItems[i]=new MenuItem();
And why would you do somethinglike this in the resize event ?
------------------------------
"The Soapbox has been so ..."

|
|
|
|
ok solved it....
altho its nothing 2 do with the resize event...
its just i need 2 re-add it to the root menuitem...

You can also use WMI (Windows Management Interface) and query for processes.

hi,
I have a class association generated from an xsd file. There is a one to many relationship that exists between the classes Order and Product.
I can set the properties for order like this: Order.Number = 1;
I can create a new instance of Products like this:
Products x = new Products();
x.name="blabla";
x.type="blabla";
now the problem is that I cannot add a Product to my order class.
I'm not sure how. plus I should be able to add multiple products to this class. The syntax is like this in my Order class:
*******************************************
private Product[] product Field;
/// <remarks>
[System.Xml.Serialization.XmlElementAttribute("Product")]
public Product[] Product {
get {
return this.productField;
}
set {
this.productField = value;
}
}
***********************************
Does anyone know the syntax to do this? or is it even possible?
I'm losing it. I've been trying to get this forever....
Please write back if you know the answer? Thanks if you do.

hi,
You can add a method to your Order class called AddProduct as follows:
<br />
class Order<br />
{<br />
.<br />
.<br />
.<br />
public void AddProduct(Product product)<br />
{<br />
ArrayList products=new ArrayList(this.productField);<br />
products.Add(product);<br />
this.productField=(Product[])products.ToArray(typeof(Product));<br />
}<br />
}<br />
Since you are storing products in an array you can not add an item to it, therefor you should use an ArrayList to add an item to the array and to cast it to the array again
Regards

Thanks so much.. Its almost working now but I needed one change.
In the first line I just had to take out the 'this.productField'
in order to get it to work. (not sure why)
it will add one object, but if i try to add another one, it just overwrites
the first one. i need to add multiple products per order. am i doing something wrong?
Thanks Again.

Hi
If you take out the first line you will lose other products that have been added to your array.You should add those items too.
Instead of
<br />
ArrayList products=new ArrayList(this.productField);<br />
write:
<br />
ArrayList products=new ArrayList();<br />
products.AddRange(this.productField);<br />
Although both methods should result the same thing ( added products so far,should be added to the ArrayList).
There's another way that I don't like and that's
<br />
ArrayList products=new ArrayList();<br />
foreach(Product item in this.productField)<br />
products.Add(item);<br />
please let me know if it's not working again
Regards

I still can't get it to work. I may be adding these lines in the wrong order.
this is how I tried implementing it:
ArrayList products = new ArrayList();
products.AddRange(this.productField);
products.Add(code);
this.productField = (Product[])products.ToArray(typeof(Product));
At least now I'm getting some sort of error in my browser. It is below. It seems like 'this.productField' is set to null at this point or something like that. I'm just confused. I'm not really following exactly what is happening here. I didn't think it would be this hard when I started. I created this class from an xsd and I thought that i would be able to add multiple sub class items automatically.
Any other ideas to what I'm doing wrong?
someone else said to try using a collection but I've never done that either and I just need to get this working as fast as possible. Thanks.
System.ArgumentNullException: Collection cannot be null.
Parameter name: c
at System.Collections.ArrayList.InsertRange(Int32 index, ICollection c)
at System.Collections.ArrayList.AddRange(ICollection c)
at RepairRequests.AddOpCode(OperationCode code) in c:\Inetpub\wwwroot\ASIAPI\App_Code\RepairOrder.cs:line 515
at Service.GetRepReq() in c:\Inetpub\wwwroot\ASIAPI\App_Code\Service.cs:line 134
at Service.GetRO() in c:\Inetpub\wwwroot\ASIAPI\App_Code\Service.cs:line 62
at Service.GetROData(String RO_ID) in c:\Inetpub\wwwroot\ASIAPI\App_Code\Service.cs:line 30

I see 
That's because productsField is null for the first time that you want to add a product
then wrtie:
<br />
....<br />
if(productField!=null) products.AddRange(productField);<br />
....<br />
or you can make it empty (instead of null):
<br />
...<br />
private Product[] productField=new Product[]{};<br />
...<br />
and there would be no need to check if productField is null in AddProduct routine.
I Prefer the second approach.

Holy crap it's working.   Thanks so much for your help and you SPEEDY responses.
I've never worked with classes in this fasion before and I'm still trying to understand what is going on here because I want to learn. Maybe you could explain this for me? Also since I don't really understand this, is there going to be multiple array lists created and cause memory issues. It seems to me like it will create a new list every time i really just want to add an object to the same list????
so this is decaling product as an empty array of type products?
private Product[] productField=new Product[]{};
new array list?
ArrayList repReqs = new ArrayList();
confusion here: to me this seems like it's creating a range of arrays?
shouldn't it be a collection of class objects?
repReqs.AddRange(this.repairRequestsField);
confusion here: now your adding an object to your array list, but how does it
know to use the new range?
repReqs.Add(rr);
confusion here: basically no clue.
this.repairRequestsField = (RepairRequests[])repReqs.ToArray(typeof(RepairRequests));
I really want to get a better grasp on some more complex c# aspects like this. Do you have any suggestions for good books?
thanks.

Hi
Yse you can declare an empty array using this syntax:
<br />
object[] arr=new object[]{};<br />
Well an arraylist is a collection object that you can add other obejcts to it(using its Add method) and it has a lot of use,you can enumurate it using its enumurator and C# foreach keyword like this:
<br />
foreach(object obj in myArrayList)<br />
{<br />
do somthing with obj;<br />
}<br />
When you use AddRange method all the members of the passing array will be added to your arraylist it's something like:
<br />
foreach(object item in myArray)<br />
{<br />
myArrayList.Add(item);<br />
}<br />
We did this here because we wanted to save the current state of our object and then add a new item to our arraylist.
Finally we convert our arraylist into a Product array again.
First we make an array from out arraylist using its ToArray() method telling it that the type of stored items is Product (typeof(Product)) then we cast our array (that so far is an object array) to a product array using (Product[]);
So we've done two tasks at one line.We could write it like this:
<br />
object[] array=myArrayList.ToArray(typeof(myClass));<br />
myClass[] convertedArray=(myClass[])array;<br />
There are a lot of good books about C# and .Net programming but what I found really useful are MSDN and this site(Code Project) you can learn a lot of things about C# and programming here.
Wrox Programming C# is a good book.
There's another book that I like "Teach yourself object oriented programming in 21 days" It's written in java though.
Anyway I'm glad that you could solve your problem and If there's anything else just I will be glad if I can help.
Regards

Hello
If you use .Net 2.0 then instead of using arrays, you should use List<product> Generic colection.
If you use .Net 1.1, then use System.ArrayList instead, as you want your array to be dynamic and grows as you add to it.
I prefered List<product> as it's type specific generic collection. Yet ArrayList will do fine.

even after entering correct username and pass.. i m redirected to login page again and again..
on the other hand when debugging the application, it works perfectly well.. m using visual web dev exp 2005
please help

Sounds like either A) A windows Permissions error as debug is run in Admin or B) The code is not synced.

Sorry to post this but, here goes.
All of the coding I've ever done, and gotten paid for it, has been VB. I'm working on a project now that I decide to do in C#. It's a breath of fresh air, let me tell ya. It reminds of my days in college doing C++ and makes me realize how brain dead doing VB can make a guy!
Anyway, what's with this escape character stuff in C# strings? I'm having a heck of a time coming up with a regular expression that will match IP addresses with leading zeros, and I think my problem may be the escape character "/". I tried replacing / with // but still no matches. In fact every regex I found on the web for IP addresses failed to match.
Here is the function:
private void RangeCheck()
{
String sLine = "";
String sIPMatcher = "(\\[0-9]{1,3})\\.(\\[0-9]{1,3})\\.(\\[0-9]{1,3})\\.(\\[0-9]{1,3})";
RegexStringValidator test = new RegexStringValidator(sIPMatcher);
StreamReader sr = new StreamReader("c:/UniqueIPaddr_list.csv");
while (!sr.EndOfStream)
{
sLine = sr.ReadLine();
try
{
test.Validate(sLine);
if (IPList.CheckNumber(sLine))
{
lstBox.Items.Add(sLine);
}
}
catch
{
}
}
}
IPList is a class I borrowed from Bo's article here[^].
And here is an example of one of 10,000+ IP address in the .csv file: 00x.0xx.xxx.0x0
where x is any number 1-9 (didn't want to disclose an acutal IP).
No matter what I try, no matches occur.  Is it my lack of C# skills, or just use of an incorrect regex?
