Sorry ... at first :
A lot of descriptions in your code are not understandable for me (because of your mother-language - Croatia ?).
What I missed was the code-part with which you have a Problem - the part where the Image-assignment is changed ...

see my answer (under this) with it's question ...

foreach (int VouType in DR)
Are you sure that VouType is an Integer ?

You can't use a SqlDataReader like that. Each record could contain multiple fields, and it would have no way of knowing which field you want to convert to an integer.
Member 12899746 wrote: while (DR.Read())
{
this.vochcombox.Items.Add(DR.GetOrdinal("VouType"));
}
That's closer, but still not right. GetOrdinal returns the index of the specified field, not the value of that field.
You need to use the GetInt32 method to retrieve the value of the field as an int.
You should also wrap your connection, command, and data-reader objects in using blocks.
public void FillCompVouType()
{
Cursor = Cursors.WaitCursor;
try
{
using (var connection = new SqlConnection(cs.sourceConn1))
using (var command = new SqlCommand("Select Distinct VouType From Table_name Where Colum=1 order by VouType", connection))
{
vochcombox.Items.Clear();
connection.Open();
using (var dr = command.ExecuteReader())
{
while (dr.Read())
{
vochcombox.Items.Add(dr.GetInt32("VouType"));
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
finally
{
Cursor = Cursors.Default;
}
}

That error is telling you that he cannot convert DR object type to int.
DR type is SQLDataReader, you cannot convert data reader to int.
Why fill "vochcombox" twice?
While loop should work, but foreach doesn't for sure.

I first learned C# then C. As I've been working in C a lot lately, I've had to do without classes obviously since it's not really an OOP language.
I've gotten rather accustomed to passing stuff in as arguments and I'm writing a C# program right now where I've been passing "state" around via the method arguments rather than the typical storing fields/properties on the class and then accessing them from the class methods. Is there anything "wrong" about doing this? Is there anything "wrong" with not using the constructor to initialize member variables to certain values and instead just using a function in the class that calls the other business functions? E.G.
someObject myObject = new someObject();
var processResult = myObject.process(someString,Processor_Option_1);
Instead of:
someObject myObject = new someObject(someString,Processor_Option_1);
var processResult = myObject.result;
Note: Option 2 also uses class state member variables whereas 1 just passes it function-to-function as argument.

No, I don't think there is anything "wrong" with your code. But the way I see it (in option 2), it is clear that your constructor is not just a constructor but also a processor, it processes the operands and then puts the result in result field.
If you are going to do this, then write them like,
SomeObjectProcessorResult myObject = SomeObject.Process(someString,Processor_Option_1);
var res = myObject.result;
This will make much more sense in C#, it does not any longer depend on the states of SomeObject (it is static), but does the same — gets input, processes and then gives out output.
public class SomeObject {
public static SomeObjectProcessorResult Process(string someString, ProcessorType option) {
}
}
public class SomeObjectProcessResult {
public Type result;
}
This is a near C# definition of types, while ignoring the states.
Then in your first option, it is clear that the function is an instance one and will depend on states of object.
TheOnlyRealTodd wrote: Option 2 also uses class state member variables whereas 1 just passes it function-to-function as argument.
Not so, you can ignore and from an external view I can easily think of implementation where I just process those parameters and ignore them (not save them). On the other hand, I can save those parameters in option 1 as state values. 
That is the case in OOP, there are side effects everywhere. If you do not want to use side effects. Consider using F#, that is a functional programming language — but does have OOP.

foreach (DataGridViewRow row in this.dataGridView1.Rows)
{
if (row.Cells(this.invoiceNO.Index).Value == true)
{
a.Add(row.Cells(this.invoiceNO.Index).Value);
}
}

|

In C#, you access array elements using [] not (),
if (row.Cells[this.invoiceNO.Index].Value == true)
This will access the elements, instead of invoking it as a function.

Or better, omit the test altogether:

Hello Every One !
Facing a issue in c# project Named(Sunny Traders) any Help will be appreciated
Error#1 " Unable to copy file "obj\x86\Debug\Sunny_Traders.pdb" to "bin\Debug\Sunny_Traders.pdb". The process cannot access the file 'bin\Debug\Sunny_Traders.pdb' because it is being used by another process"
Error# 2 "Could not copy "obj\x86\Debug\Sunny_Traders.pdb" to "bin\Debug\Sunny_Traders.pdb". Exceeded retry count of 10. Failed. Sunny_Traders"
What i tried is
1.Adding Exception in Antivirus
2.Change in Release and Debug
3.Cleaning Project and Rebuilding
4. What is working for me is to Close VS and delete all files from project->bin->debug ( Sadly i have to repeat No.4 Every time to execute.
waiting for a Solution

That is the way it works. Rebyc Rebyc wrote: because it is being used by another process"
All that needs to be done is terminate that program, because you are executing a write operations on a file and in Windows, files are locked from any write operation. Just terminate that program so that content can be updated, then restart the service. You are right, you have to repeat this process, otherwise do not start the debuggers until everything is in its place.

I made this but it doesn't work well!!!
private Dictionary<char, int> numbers;
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
string number = tbHint1.Text + tbHint2.Text + tbHint3.Text + tbHint4.Text + tbHint5.Text + tbHint6.Text;
numbers = number.GroupBy(c => c).ToDictionary(g => g.Key, g => g.Count());
if (char.IsDigit(e.KeyChar) || char.IsSymbol(e.KeyChar))
{
char keyPressedByUser = e.KeyChar;
if (!number.Contains(keyPressedByUser))
{
e.Handled = true;
return;
}
int inputCount = textBox1.Text.ToUpper().Where(c => c == keyPressedByUser).Count() + 1;
if (inputCount > numbers[keyPressedByUser])
{
e.Handled = true;
return;
}
e.Handled = false;
}
else
{
e.Handled = true;
}
}
