I need to determine whether each character in the first string can be uniquely replaced by a character in the second string so that the two strings are equal.
Like this:
for "eef" and "ddg"
Result :
True e => d
f =>g
If I have: "efe" and "ddg" the result is "False" because "e" it has "d" and "g". (strings are equal in length)
I need help with the starting point, I made an array to store the characters from input strings and I was thinking to use IndexOf method after that, to return the indexof each character and compare it with the second string. I'm not sure how to implement this.

And?
What does it do that you didn't expect, or not do that you did?
What have you tried to do to find out why?
Are there any error messages, and if so, where and when? What did you do to make them happen?
What help do you need?
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

Think about how you would do it manually, with a pencil and paper.
When you have that down pat, the code should be pretty easy.

Make an array with a position for each character code, each element a character and a bool, initialized to nul and true. Scan the two input strings S1 and S2 in parallel. Use the S1 char as index in your new array. If its char is still nul, change it to the S2 char. If it is something else, but different from the S2 char, set the bool to false. After reaching the end of S1/S2, if there are any entry in you new array with the bool set to false, the result is false.
I am sure that your professor will accept this solution method for your homework.

Strings can be treated as an array of characters so you don't have to create "input arrays".
string a = "eef";
string b = "ddg";
Dictionary<char, <list<char>> dic = new ...
if ( a.Length == b.Length ) {
for ( int i = 0; i < a.Length; i++ ) {
if ( dic.ContainsKey( a[i] ) {
}
}
}

Hello, and thank you for your time to look out my question.
I forgot to say that I have to use only System, not list or dictionary, LINQ, and others. The course assignment requirements. I think that is more about the logic

Hi Friends,
I have a scenario where need to generate WordProcessing Report
Here is my template sample below
First Name: «FirstName»
Last Name: «LastName»
Here First Name and Last Name are keys and corresponding Merge-fields are («FirstName» & «LastName»)
Now I have to generate a report where these key and merge-fields need to repeat number of times according to the Employee record. Example if there are fice employees in database, i need to show all five employees record one after other with FirstName and LastName in sequence.
I tried with below code. But this wont help because the key and data value does not show as per template configuration.
Can you please tell me how can i achieve this in C#?
Thanks in advance.

You could achieve it faster in MS Word.

Search and replace; should be simple enough. What part of the code are you struggling with?

For some reason when I display icons in the ListView control, they are slightly fuzzy, or blurred.
I'm taking the icons from executable files and displaying them next to the filename, like Windows File Explorer.
But in Windows File Explorer, the icons are crystal clear.
I have the color depth of the ListView image list set to 32 bits.
Anyone have an idea?

Sounds more like a resolution problem. Icons do not rescale well. Can you access different size icons from the exe?

Yes, I can probably extract different sizes. The icons are being extracted by the ExtractIconEx Win32 function in a native DLL.
Does the ListView control offer the capability to display the same icon(s) at different sizes? So far I've only seen one small size and one large size.

Beyond my pay grade, I'm sorry. Ask an expert.

All I can do is ask everybody and hope an expert answers.

I assume this is related to your other question in the C/C++ forum. Are you sure you are extracting the correct icon, i.e. having the size that matches the ImageList properties?
|
|
|
|
|
I create the Icon object using the FromHandle method passing in the HICON of the extracted icon.
And when I check the size of the new Icon object, it reads 32 x 32, which is the same as the size I set for the ImageList.
Maybe the ListView is just bad at displaying icons?

Great idea! I'll try that.
Thanks Richard.

Didn't think it would be necessary to ask: WPF, Windows Forms or UWP?

Windows Forms.
I tried Richard's suggestion of converting the icon to a bitmap before adding it to the ImageList, but that didn't fix the fuzziness.

This sounds interesting:

I don't see anything on that page that makes any difference.
Thanks for your taking the time to respond.

Without seeing any code I don't know if this will help. I fixed this problem in VB by converting the icon to a bitmap with the routine below. I also use ExtractIconEx. I found that icon.ToBitmap() loses resolution for some reason. Sorry, you'll have to convert to C#.
''' <summary>
''' Convert Icon to Bitmap with resizing.
''' </summary>
''' <param name="ic"></param>
''' <param name="sz"></param>
''' <returns></returns>
''' <remarks></remarks>
Public Shared Function IconToBitmap(ByVal ic As Icon, ByVal sz As Size) As Bitmap
If ic Is Nothing Then Return Nothing
Dim sourceWidth As Integer = ic.Width
Dim sourceHeight As Integer = ic.Height
Dim dPercent As Double = 0
Dim dPercentW As Double = 0
Dim dPercentH As Double = 0
dPercentW = (sz.Width / sourceWidth)
dPercentH = (sz.Height / sourceHeight)
If (dPercentH < dPercentW) Then
dPercent = dPercentH
Else
dPercent = dPercentW
End If
Dim destWidth As Integer = (sourceWidth * dPercent)
Dim destHeight As Integer = (sourceHeight * dPercent)
Dim bm As Bitmap = New Bitmap(destWidth, destHeight, PixelFormat.Format32bppArgb)
bm.SetResolution(destWidth, destHeight)
Dim g As Graphics = Graphics.FromImage(bm)
'g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
' This gives the best quality
g.InterpolationMode = Drawing2D.InterpolationMode.NearestNeighbor
g.DrawIcon(ic, New Rectangle(0, 0, destWidth, destHeight))
g.Dispose()
Return bm
End Function
