Hey Guys, I am kind of looking around at a couple different places for answers here, got some help from some great folks here before so here goes!

I am working on, same project as I have always been working on, just adding more stuff lol. In this project I want to call an ini setting into a combo box. Here's where I am, I can list the directories into a comboBox, and I can read a line from an ini from a single location into a combo box. Now, I need to take this one step further. I need to list that ini setting in the comboBox, from within all those directories. All ini files are named the same thing, but the context is different in the ini field. So basically, I have two pieces two a puzzle figured out, that I need to make fit. Here's an example of what I can do, and what I want it to do.

//I can list the directories into a combo box using this
//Inside the FOLDERS directory are three folders, Folder1, Folder2, and Folder3.
//They are what is displayed in the comboBox.
DirectoryInfo obj = new DirectoryInfo("C:\\Users\\first.last\\Desktop\\Projects\\Test Files\\Folders\\");//you can set your directory path here
DirectoryInfo[] folders = obj.GetDirectories();
comboBox.DataSource = folders; // Populate combobox

Ok, so that's simple enough. What I want to do is take the values of my choice from the code below and list them from EACH directory into the comboBox. There could be any numbers of folders in that directory, but that shouldn't matter.

Here is how I show my ini settings now

IniFile ini = new IniFile("C:\\Users\\first.last\\Desktop\\Projects\\Test Files\\Folders\\Folder1\\Settings.txt");
comboBox.Text = ini.IniReadValue("Info", "Name");

Here's what I WANT to be populated in the comboBox at time of load.

IniFile ini = new IniFile("C:\\Users\\first.last\\Desktop\\Projects\\Test Files\\Folders\\" + Search.All.Folders.For + "\\Settings.txt");
comboBox.Text = ini.IniReadValue("Info", "Name");

I am not sure if that is even how it would be done, but I want to list that value in the combo box, for each folder that has that settings.txt.

If I need to clarify anything, please let me know, I can also provide a complete example of my source code if someone needs it zipped up for them. Thank you!

EDIT:

So I see I have gotten quite a few views of this and maybe it is a bit confusing. Here is how I theorize this happening, but needing guidance on making it a reality.

Couldn't I define folders as a string, and do something like
For Each (Folder) //(meaning it will do this block of code for each item in the string, being the folders in the specified directory)
{
IniFile ini = new IniFile("C:\\Users\\first.last\\Desktop\\Projects\\Test Files\\Folders\\" + Folder + "\\Settings.txt");
comboBox.Text = ini.IniReadValue("Info", "Name");
}

Edit #2 - I am going back through my C# tutorials because I remembered something that I learned about the while statement, I thought I could apply it in this case but am having no luck making "folders" turn into a string to even remotely make this possible. I am referring to www.learnvisualstudio.net video number 2010_02_06.
Here was my theory....

string thisFolder = folders; //I can't make this a string because it is already declared and I can't convert it to a sting implicitly...
while (folders != null)
{
//execute
IniFile ini = new IniFile("C:\\Users\\first.last\\Desktop\\Projects\\Test Files\\Folders\\" + thisFolders + "\\Settings.txt");
if (folders = null)
{
comboBox.Text = ini.IniReadValue("Info", "Name");
}
}

In my head this sounded as if it would have worked. But this just isn't the way things work lol...

I'm not absolutely clear what you are trying to do - it may be that I need more coffee - but I think you are trying to supply a root folder and access all the files under that that are called "settings.txt", then read a setting value from each of those and display them all in a combobox.

If so, then I think you are trying to force the wrong methods to do the job. Lets just step back a litle and look at the task:
Find all files called "settings.txt" somewhere in a folder heiracrchy.
Well, you are locating att teh top level folders under the root ok with DirectoryInfo.GetDirectory, but that isn't quite what you want. Not only does it return a DirectoryInfo object (which contains the string you think you want in the FullName property) but there is a much, much easier way to do exactly what you want:

string[] SettingsFiles = Directory.GetFiles(@"D:\Temp\", "Settings.txt", SearchOption.AllDirectories);
foreach (string file in SettingsFiles)
    {
    Console.WriteLine(file);
    }

You can then simply read each file since you have it's full path and name.

Doesn't this do what you want?

I completely boogered my project. I have to rewrite everything and test what you got there. I think I need to go one step further with what you gave me there though. It looks like that just gives me the paths to the directories that contain a file called settings.txt, which is great thats the first step.

Here's a layout of sorts to illustrate what I want to accomplish.

There are 3 folders with the settings file.

D:\Temp\Folder1\Settings.txt
D:\Temp\Folder2\Settings.txt
D:\Temp\Folder3\Settings.txt

in the text file, I have settings that look like this
[Name]
name=

and the ini code I have up there grabs the verbage in that section. So let's say the names are like this:

Folder1 - name=John
Folder2 - name=Sam
Folder3 - name=Zach

I want the comboBox to have a list like this:

John
Sam
Zach

I hope that helps understand my goal. Thank you for your reply! I am working on rebuilding my project right now. Smile | :)

Not quite - if you add a button to your form and run that code in the button click, you will find it prints the full path to all the files called "Settings.txt". So all you have to do is feed the string into your IniFile constructor and access the file:

IniFile ini = new IniFile(file);

You can then add each setting value to your ComboBox Items collection. You don't want to set the Text property each time, because that will only show the last value you set into it - it is just a string property after all! Laugh | :laugh:

So let me make sure I understand this correctly, and please forgive me as I am completely novice and am running through as many training videos as I can all the while trying to dream big with my own personal projects.

After I generate that information, I just need to plug this into a button (or form_load as intended):

IniFile ini = new IniFile(file);
comboBox = ini.IniReadValue("Info", "Name");

and it will simply fill my combo box with my desired settings? I have a feeling I am wrong as this sounds too simple, or maybe I just hit the jackpot on my biggest hurdle. Thank you so much for working with me. Smile | :)

OriginalGriff9-Mar-13 23:42

9-Mar-13 23:42

Not quite that simple - you need to use both bits of code, and you can't assign a string to a ComboBox variable! Laugh | :laugh:

Try something like this:

string[] SettingsFiles = Directory.GetFiles(@"D:\Temp\", "Settings.txt", SearchOption.AllDirectories);
comboBox.Items.Clear();
foreach (string file in SettingsFiles)
    {
    IniFile ini = new IniFile(file);
    comboBox.Items.Add(ini.IniReadValue("Info", "Name"));
    }

BTW: you probably don't need the "Ini" part on the method name "IniReadValue" - it is implied by the fact that it's an IniFile method.

Question that came into my mind whilst I am close to being done rebuilding. Can I change the SearchOption.AllDirectories into something more specific? In case I copy and paste a directory to make a backup of the original settings? Like for instance, only look in folders that BEGIN with "BRD"? Thanks again.

SearchOption = "\\BRD*"); <--- just an example of what I mean

Edit: Ok it's all built. I am now running into an exception. Apparently, the name IniReadValue does not exist in the current context. But it exists in my ini class.

public string IniReadValue(string Section,string Key)
{
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section,Key,"",temp,255,this.path);
return temp.ToString();

}

OriginalGriff10-Mar-13 0:55

No - the search only considers file names, it doesn't compare against the path. But it's pretty easy do check afterwards:

if (file.Contains(@"\BRD"))
   {
   ...
   }

Exception: (I suspect it's a compilation error?)
Show your code (cut'n' paste so you don't mistype - and try using the "code" widget above the text box to format your code - it makes it easier to read)

Remember that c# is case sensitive:

                IniFile ini = new IniFile(file);
                comboInst.Items.Add(Ini.IniReadValue("Info", "Name"));
------------------------------------^

Becomes:

                IniFile ini = new IniFile(file);
                comboInst.Items.Add(ini.IniReadValue("Info", "Name"));
------------------------------------^

You need to make the two names match!

We have a Winforms form containing a textbox. The idea is that as you enter a string of hex characters these are trapped and are used to change the background colour of the texbox dynamically. So, if you enter ff0000 that would change the background colour to red. The user keystrokes are intercepted with the KeyPress and KeyDown to filter specific characters such as not allowing G, Y that sort of thing. All of this works okay and the texbox's text changed event correctly changes the colour.

The text in the textbox is mostly visible. If I set the foreground colour of the text to black there's no problem if you set the background colour to red (ff0000), blue (ff) but when you set it to black (0) or just-a-bit-away-from-black (1) you obviously can't see the text. If I set the forecolour of the text to white you get the same problem at the other end of the colour "spectrum". I thought of using grey as that's sort of midway but if you set the background colour to (808080) or near to then, well, you can see the problem! Smile | :)

The idea I hit upon and which works relatively okay is to invert the bits of the RGB and set the foreground colour to that. So, depending on what's entered you might have a background colour of slightly-purpley-reddish-orangey-blue and the text might look like whitish-green-yellow-tinged-magenta-with-a-touch-of-russet-but-not-too-much.

It works upto a point if you don't mind your foreground colour looking like it's injected pure LSD but I'm wondering if there's a more optimal solution or suggestion you'd recommend? In other words, is there a good solution so that no matter what the background colour is set to, the foreground colour of the text within it can be displayed with a best fit contrast?

Hello,

I have couple of question about if statement.

When I create password verifying program,

at least 8 characters long is
if (password.Length < 8)
valid = false;

like this, right?

Then, how can I make program that must contain at least one digit and one uppercase for the password.

Then, I tried to create
while (valid && i < 1)
{
if (!Char.IsLetter(custID[i]))
valid = false;
i++;
}
like this, but it's not working.

Please tell me.
