I am working on a school project which calls for a random number based on user input and unfortunately I cannot seem to find how to do this. My book does not offer a very good explanation of this and when I search for this online I get some very confusing results. Here is the problem in a nutshell:
I am creating a math game to be used by children. They need to provide which operator they want and choose the maximum numbers to use when generating the problems.
My random generator needs to be based on what the maximum numbers are. For example:
User input:
maxNumber1: 5
maxNumber2: 10
random generated problem:
5+10 (or any other problem using 1-5 and 1-10)
I am not asking for anyone to solve my problem for me but I would appreciate a little direction as to where I can find the answer that would pertain to this scenario.
Thanks in advance!

Without negative values? I guess you should look at Random.Next(int)[^]
Don't forget to only create 1 instance of Random, don't make a new one every time (ok I know it's not like it will really matter in this case, but it's still bad practice to do it)
|
|
|
|
|
For instance:
Random RandomClass = new Random();
// The Next method should be called with two arguments: the minimum value and the maximum value.
int RandomNumber = RandomClass.Next(maxNumber+1, maxNumber+2);

Code requests are not entertained here.
Look at the constructors of the MessageBox class. It has few options. If that does not suites, create your own.
|

The MessageBox is a build in Windows dialogue, not even really .net. You can't change the button text, though there are many combinations of buttons you can show.
You will have to replicate it with your own Form and then you have total control over the buttons.

CodeProject is a beautiful website. It has many features. One of the most important features is "SEARCH".
A simple search for message box could easily have given you some suggestions for your answer.

Noone is going to give you a source code. If you show some proof that you have done some work, people here will help you.
In any case, have a look at this Article on CodeProject: XMessageBox - A reverse-engineered MessageBox()[^]

I am having an issue with a Fax component. It works when installed on a WinXP machine, but has an exception on Server 2003.
Here is my exception:
The COM class factory for component with CLSID {D73733C8-CC80-11D0-B225-00C04FB6C2F5} failed due to the following error: 80040154.
I found a couple of articles stating that this is a problem seen in 64-bit operating systems. I have personally confirmed that neither system is 64-bit, yet the problem persists (no exception in XP, exception in server 2003).
This is my first time using FAXCOMLib, so if I am making some rookie mistake please let me know. Thank you!
Here is the section of code that is failing:
FAXCOMLib.FaxServer faxServer = new FAXCOMLib.FaxServerClass();
faxServer.Connect(Environment.MachineName);
FAXCOMLib.FaxDoc faxDoc = (FAXCOMLib.FaxDoc)faxServer.CreateDocument(file.FullName);
faxDoc.RecipientName = recipientName;
faxDoc.FaxNumber = faxNumber;
faxDoc.DisplayName = displayName;
faxDoc.Send();
faxServer.Disconnect();

It should be easy to fix it:
It means that your module is not registered, so you have certainly copied the library to your target system without registring it.
* regsvr32 xxxx.dll if you have an error use a tool to check if a missing dependency is not missing (dependency [^]
Keep update us.

OK, the COM problem is fixed - the Windows Fax service was not configured on the account the prog is using. (Apparently Windows fax must be configured for each account?)
However, a different exception is being thrown by the same code block:
Access is denied. (Exception from HRESULT: 0x8007005 (E_ACCESSDENIED))
So apparently, it has permissions issues in reaching the Fax service...

The difference maybe in UAC control which may prevent to load the DLL or to access a specific resource.
Look at this policy explainations for more details:

Because, remotely it will be difficult to find any potential security reasons. Depending on the installation and the way you have installed your software. 
Good luck. Keep us updated.

There is a License agreement dialog which can be added to the set up project. Try that.

I have not used DataGrid, but looking at the properties it offers, I guess painting it yourself should help.

If I recall correctly, since .net 2.0, the cells have had a background color property.
However, back when I was thinking of doing that, I decided to use a TreeView instead -- I avoid data grids whenever possible.

I have <Contact> nodes within <Contacts> elemnt and I am binding it to a datagrid using ReadXML. If I place a button for MOVE UP and another button for MOVE DOWN, the how can I re-position the nodes in the XML file?
|
|
|
|
|
I would use XPath or XmlDocument and then rebind the grid.
