It could probably exist but I dont see the logic behind the three buttons as there is no way apart from using a modal popup to force someone to click x or y button before proceeding. Hence the point that the button is modal.
Because with your method they can click the doStuff button without clicking either other one. The doStuff button can then not force the clicking of either of the other buttons, it is still down to the users choice unless you lock them out using a modal form.
The adaption to Deceptikon's response here would be to make a custom form that looks like a message box proving two buttons, 1 and 10, and then use .ShowDialog() on the customer form to display it modally, therefore forcing a response to the form before continuing.
You could then assign the form returning a yes reponse to the 1 button and a no to the 10 button creating what you require.
You may need to tweak my variable declaration to get the length right, but you were overwriting the originals passed in as well as returning them to the new array as output.
You have two options to convert a string to an integer, convert and tryparse.
string TempString = 0;
int OutInt = Convert.ToInt32(TempString); // This will exception if not viable to convert to integer
string TempString = 0;
bool Success;
int OutInt;
Success = int.TryParse(TempString, out OutInt); // This will return true if the convert was successful and false if it wasn't but will NOT exception and is generally the better practice.
using System.Text;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
Cassandra myObject = new Cassandra();
string a ="söt";
a = myObject.hejsan(a);
System.Console.WriteLine(a);
Console.ReadLine();
}
}
class Cassandra
{
public string hejsan(string value)
{
value +="Cassnadra";
return value;
}
}
}
Line 10, you need to assign a to be the output of the method, as I have done in the above code.
public string[] CreateCards( string[] Cards)
{
Cards = new string[52];
for (int a = 0; a <= 51; a++)
{
if (a <= 12)
{
Cards[a] = " Hjärter " + (a+1).ToString();
}
if (a > 12 && a <= 25)
{
Cards[a] = " Ruter " + (a-12).ToString();
}
if (a > 25 && a <= 38)
{
Cards[a] = " Spader " + (a-25).ToString();
}
if (a > 38)
{
Cards[a] = " Klöver " + (a-38).ToString();
}
}
return Cards; //i get wrong here saying i need to return an array and Cards[] wont work
//because they expect a value
}
Need to add [] to the return in method declaration to make it an array.
So... I must not be reading the other part of the SQL Correctly. I'm not to sure what this part means.. ={0} ?? what is this trying to reference?
Right to explain this. The following two lines of code do the same thing.
Console.WriteLine("The cat sat on" + " the " + "mat.");
Console.WriteLine(string.Format("The cat sat on {0} mat.", "the");
Basically the second line allows you to insert the values after the actual text string, so in the above case, the string "the" is added where {0} is. For longer strings with multiple entries it is simply comma-seperated values after the string like so:
Console.WriteLine("The {0} sat on the {1} and the {2} ate it.", "cat", "mat", "dog");
Obviously the strings can be replaced with any sort of variable, in your case the .Tag property.
Basically it keeps strings cleaner that concatenating everything with +'
Its declared but isnt instanciated (I could be completely wrong here, and it wont make a difference) but try: DataTable cashOrderTable = new DataTable(); on line 15.
Ok sorry for this not being actual code but its quicker for me to write to the code in a descriptive process and answer questions than mess around with setting up fake datasets and then try to SQL them (been trying for the last 20 mins and failing).
To bind a listbox to a data source.
Dataset: DS
For example we have a table called CustomerTable with two rows CustomerID and CustomerName, will assume we have already run the SQL to select this information and it is in the dataset DS
And a second called OrderTable with rows OrderID, CustomerIDFK and ItemID which we will be running SQL off.
Our listboxes are List1 and List2.
To setup our first list with the customer names and their ID's as the selected value:
List1.DataSource = DS.Tables["CustomerTable"];
List1.DisplayMember = "CustomerName"; //The column name as a string
List1.ValueMember = "CustomerID";
So now in the SelectedIndexChanged action of the listbox List1 we will run an SQL query to the second table.
string SQLToRun = string.Format("Select * From OrderTable Where CustomerIDFK = {0}", List1.SelectedValue); //The string.Format allows use of {0} and then specifying the value after the end of the string, makes it a bit tidier than cutting off the string at '=' and then concat'ing the .SelectedValue in
This would return all the rows matching the CustomerID selected in List1 (it probably wouldnt as im rusty with SQL but oh well!)
And then following the same steps as with List1 we …
@nmaillet, Didn't know you could leave the second part of the count specifier blank for any amount :)
@nesa24casa - the fix for my solution with your updated requirements using nmaillet's capturing. Also made it so it captures both <tab> and \t for the sake of covering all options :) simply remove |<tab> from the regex if you dont need it covered
You would need to set up the first list so that the .SelectedItem in list box (What you can physically see) is as you state above, but the .SelectedValue contains the actual ID value.
Then the SQL can adjust too: SELECT ID,QTY,Description,Supplier,Date,Cost,Sell from cashOrders INNER JOIN cashCustomers ON cashOrders.cashAccountRef_FKID=cashCustomers.CashAccRef WHERE cashCustomers.CashAccRef = " + listview1.SelectedValue;
Havent tested this so the SQL might not work but thats the jist of it. It basically selects all the required information from the cashOrders table based on the Id linked to the cashCustomers table where we compare that to the passed ID value from the .SelectedValue of the listbox1.
In terms of binding the listbox to get the information working correctly, if I remember rightly, it is done by binding the listbox to the datasource and then specifying which columns are the .DisplayMember (is visually seen) and .DataSource.
That probably isnt explained clearly as its been about a year since I've done such xD
Sorry, easy fix, replace the current bottom if statement with:
if (countNum != skipNum)
{
// Use static Path methods to extract only the file name from the path.
fileName = System.IO.Path.GetFileName(s);
destFile = System.IO.Path.Combine(targetPath, fileName);
System.IO.File.Copy(s, destFile, true);
skipNextFiles = true;
}
Code is tweaked and tested. With a skipNum of 2, I got files copied: 1, 2, 5, 6, 9, 10 of 10 files.
static void Main(string[] args)
{
string fileName;
string destFile;
string sourcePath = @"C:\Users\maskew\Documents\DaniWeb\Source";
string targetPath = @"C:\Users\maskew\Documents\DaniWeb\Destination";
// To copy all the files in one directory to another directory.
string[] files = System.IO.Directory.GetFiles(sourcePath);
// Copy the files and overwrite destination files if they already exist.
bool skipNextFiles = false;
int skipNum = 2; //as per the example, set this however you like.
int countNum = 0; //used to track how many files copied since last skipped file.
foreach (string s in files)
{
if (skipNextFiles)
{
if (countNum != skipNum)
{
countNum++;
if (countNum == skipNum)
{
countNum = 0;
skipNextFiles = false;
}
}
}
else
{
if (countNum != skipNum)
{
// Use static Path methods to extract only the file name from the path.
fileName = System.IO.Path.GetFileName(s);
destFile = System.IO.Path.Combine(targetPath, fileName);
System.IO.File.Copy(s, destFile, true);
countNum++;
if (countNum == skipNum)
{
countNum = 0;
skipNextFiles = true;
}
}
}
}
}
static void Main(string[] args)
{
string fileName;
string destFile;
string sourcePath = @"E:\Source";
string targetPath = @"E:\Destination";
// To copy all the files in one directory to another directory.
string[] files = System.IO.Directory.GetFiles(sourcePath);
// Copy the files and overwrite destination files if they already exist.
int skipNum = 1; //as per the example, set this however you like.
int countNum = 0; //used to track how many files copied since last skipped file.
foreach (string s in files)
{
if (countNum != skipNum)
{
// Use static Path methods to extract only the file name from the path.
fileName = System.IO.Path.GetFileName(s);
destFile = System.IO.Path.Combine(targetPath, fileName);
System.IO.File.Copy(s, destFile, true);
countNum++;
}
else
{
countNum = 0;
}
}
}
Have written this in the reply without testing but its pretty simple so should work hopefully, lemme know any errors and i'll resolve.
It is worth noting if you are not running a multi-threaded application the load bar will not update normally as the form will 'freeze' until the whole thread has run, ie. bar will jump from 0% to 100%.
It is worth reading the "Read before posting" post next time Q8iEnG.
B – Please Uninstall or Disable any P2P (peer-to-peer) programs on the infected computer before posting in this forum. Rather than write a long piece on the dangers of P2P, I’m just going to say this: P2P software circumvents common-sense security measures and opens a user’s computer to a world of hurt. Our regular volunteers' time is valuable and most are not willing to waste it on a machine that is almost certain to be reinfected in short order. So, please remove or disable all P2P software for the duration of the cleaning process. Failure to do so may result in your thread being ignored.
