Hi!
As you suggested, I tried the example in

https://msdn.microsoft.com/en-us/library/system.windows.forms.form.load%28v=vs.100%29.aspx[^]

Had to change the code a bit, but managed to get it working and added a Form1_Shown event as well. Two things:
1) IMHO, I think that's what I need instead of a Form1_Load event, because I want to add something after the form has loaded and displayed all the controls with their initial values.
2) I have a bigger question now: What's the practical difference between the load event and the constructor code that I can write at the beginning of the form, right after the InitializeComponent() part?
Can you help me? THANK YOU, again!

Hi
I am in need of help please as I am not familiar with the folder permissions stuff.

Everyone has access to a particular folder where the files are held.

Q1. The folder permissons have 'EVERYONE' set to tick on everything

Full control
Modify
Read & Execute
List Folder contents
Read

There is also [company name]/Administrators - they have the same settings as above.
There is another group for everyone [CompanyName]/[CompanyName]

How can we prevent access to this folder for everyone?
The problem is in the VB.Net application, there are some forms that creates a file in that folder and 'everyone' who logs into this application are allowed to generate a file
that is written to this folder BUT we don't want them having access to the folder to see all the files.

The software (VB.Net) actually generates files by a logged in user but they shouldn't be able to access the folder when they go to the My Computer->Network->Folder.
We need to make sure it is creating the files and can view documents within the software only.

What can be done on the folder for Q1?

Would appreciate the help

Considering a Windows Forms application runs AS THE USER THAT LAUNCHES IT, so your security isn't really going to work. At BEST, what you're going to be able to do is prevent users from casually looking in the folder to see, well, nothing. The user wouldn't be able to see the files in the folder. All you have to do is turn off the "List folder contents" permission.

I said "casually" for a reason. Users and/or administrators will still be able turn that permission back on and easily see the files in the folder.

You basically have no recourse to do what you want. In order for the application to work on the files it needs to it needs a certain minimum set of permissions. That means that the users running the application need those permissions. You set permissions on users and groups of users, not applications.

Oh, and nothing in a forum environment is "urgent". Everyone here volunteers whatever time they have to answering questions on forums.

you need to change the user that your application is running under. see samples:

Accordion in windows Forms

Could someone help in understanding with examples of multiple controls in a Panel which is in an Table layout and should behave like web Accordion? I have gone through the websites and other tutorials but none of those examples have real time scenarios. So it is very hard to find the exact procedure of accordion will act in windows forms with multiple controls like textbox, combo box, checked list box, button etc. I would like to have one such article with real time Examples of Code snippets from SA because this concept has not been explained properly anywhere in google with snippets and examples

Your help is much appreciated.
Thanks
Happy Coding!

Oops. I am sorry. I don't want to help me in writing an article. I actually wanted an article/ tutorial to understand accordion in windows forms. I am working on windows forms and I wanted to do something like in Web Accordions. That's the only intension.

Your help is much appreciated.
Thanks

Meaning I worked on one such form and I tried to create my own code for accordion. But my form has only label as control. If I add more controls, I do not know how to proceed for accordion. Real time meaning: which has most used the controls in the form like combo box, listbox, button etc

Your help is much appreciated.
Thanks
Happy Coding!

OK let me put this again Clear. You must be knowing for Accordion in Web applications work.
I want a similar one in windows. I already did try. But If my panel has any other controls other than Label, it doesn't work. Could not figure it out how to achieve this with all the controls in the panel.
Here is the code that will act labels click as accordion

Private Sub ButtonClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label2.Click, Label3.Click, Label5.Click
    'find out which label was clicked
    Dim lbl As Label = CType(sender, Label)
    'find the panel containing the label
    Dim pnl As Panel = lbl.Parent

    For Each p As Panel In TableLayoutPanel1.Controls
      Dim l As Label = CType(p.Controls(0), Label)
      If p.Equals(pnl) Then
        'expand or collapse the panel
        If p.Height = 150 Then
          p.Height = 25
          l.ForeColor = Color.Black
        Else
          p.Height = 150
          l.ForeColor = Color.Black
        End If

      Else
        p.Height = 25
        l.ForeColor = Color.Black
        l.Image = My.Resources.arrow
      End If
    Next
  End Sub

My French is limited to "Je suis un croissant" Cool | :cool:

Still, according to the headline you'd want to print a datagrid with VB.NET, which sounds reasonable enough. There's an article here[^] that targets VB, but most documentation and examples would be in English, not in French.

Out of curiousity; what country are you from?

Cool

The forums are primarily based on English*. Having a single language makes it easier for all, as it means we need not translate all technical documents. It has the added benefit that we can communicate regardless of the official language in the country. I'm going to assume English was the natural choice, being the simplest (or most widespread) of the bunch.

Your headline was fine. If you're unsure, use Google Translate.

*) with two major exceptions Smile | :)

Hi There,

I'm about to make a small application Windows Form/C# to keep different kind of informations such as passwords credit card info etc.
It is rather simple with a treeview on the left side and a listview on the right side.
Now I implement 'Search' and 'Find next' and it works fine so far in both views. However when I find and highlight a hit in a listview subitem the entire cell (background) is highlighted but I only want to highlight the text itself.

(I would like to add some screen shots but I don't know how to do it).

Any ideas how to solve this (code example are very much appreciated)?

Thanks in advance,

Hi Eddy,
Thanks for your reply. I already had a look at that link and https://msdn.microsoft.com/en-us/library/system.windows.forms.listview.drawsubitem(v=vs.110).aspx[^] as well.
However that example as well as others draws the entire cell in the same color.

My problem is that I'm not a very skilled C#/.NET programmer, but I'll try to dig deeper into that subject.

When/if I find a solution I'll post it here.

Take a look here[^]

This control can do all that... And a whole lot more! You will have to completely redo anything already using a list view, though, but the added power and flexibility is well worth it.

Just take note of the license being GPLv3.

I have used this control before, and it is AWESOME!
