Can any1 finish this 7 panel back and forth code for me? ( C#)

Question

I hate to ask this question but I seriously need help. There are already 3 panels in the code that the buttons switch through. What I need is for it to switch through 7 different panels. The reason why im asking help on this is because ive been up over 48 hours working on a project and I need some sleep and its due by next monday...Also I have a lot of family stuff to do this weekend so ill only get 1-2 days to finish the rest including animations so if anyone can please do this for me it would make my life a lot easier. private void Form4_Load(object sender EventArgs e) { btn1.Enabled = false; PanelSwitcher(); btn1.Click += btn1_Click; // back button btn2.Click += btn2_Click; // forward button } int counter = 0; int maximum = 2; //Maximium = total panels started from 0 1 2 private void btn2_Click(object sender EventArgs e) { int original = counter; counter++; //the ++ after a integer raises the value by 1 if (counter > maximum) counter = maximum; btn1.Enabled = true; // counter must be at least 1 so enable back button if (counter == maximum) //checks to see if counter is equal to that of maximum { btn2.Enabled = false; // disable forward button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void btn1_Click(object sender EventArgs e) { int original = counter; counter--; if (counter btn2.Enabled = true; // counter must be less than maximum so enable forward button if (counter == 0) { btn1.Enabled = false; // disable back button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void PanelSwitcher() // no longer a timer Tick handler { switch (counter) { case 0: panel1.Visible = true; panel2.Visible = false; panel3.Visible = false; break; case 1: panel1.Visible = false; panel2.Visible = true; panel3.Visible = false; break; case 2: panel1.Visible = false; panel2.Visible = false; panel3.Visible = true; break; } } } }

All I can tell you is that my 'model' of the application works fine using that code. My panels are in a stack are exactly the same size but different colors. Whilst I can't see what difference it would make if you've now settled on 4 panels then you could try the longer version of the code instead: private void PanelSwitcher() { switch (counter) { case 0: panel1.BringToFront(); panel1.Visible = true; panel2.Visible = false; panel3.Visible = false; panel4.Visible = false; break; case 1: panel1.Visible = false; panel2.BringToFront(); panel2.Visible = true; panel3.Visible = false; panel4.Visible = false; break; case 2: panel1.Visible = false; panel2.Visible = false; panel3.BringToFront(); panel3.Visible = true; panel4.Visible = false; break; case 3: panel1.Visible = false; panel2.Visible = false; panel3.Visible = false; panel4.BringToFront(); panel4.Visible = true; break; } } The maximum field should of course now be set to 3.

I just got it to work...There was either somthing a bit wrong with the code or I was doing somthing wrong. The panel 2 was only showing as I was going back so instead I made panel 2 false and panel 3 true. Now its going back and forth perfectly.

Vulpes · Answer

If you wanted to add a fifth panel then yes that would be the code though it's starting to get tedious to write out which is why I came up with the abbreviated version when you mentioned seven panels.

Caleb Dunn · Answer

Thanks I understand now...So if I wanted to add a 4th panel the code would be... private void PanelSwitcher() { switch (counter) { case 0: panel1.BringToFront(); panel1.Visible = true; panel2.Visible = false; panel3.Visible = false; panel4.Visible = false; panel5.Visible = false; break; case 1: panel1.Visible = false; panel2.BringToFront(); panel2.Visible = true; panel3.Visible = false; panel4.Visible = false; panel5.Visible = false; break; case 2: panel1.Visible = false; panel2.Visible = false; panel3.BringToFront(); panel3.Visible = true; panel4.Visible = false; panel5.Visible = false; break; case 3: panel1.Visible = false; panel2.Visible = false; panel3.Visible = false; panel4.BringToFront(); panel4.Visible = true; panel5.Visible = false; case 4: panel1.Visible = false; panel2.Visible = false; panel3.Visible = false; panel4.Visible = false; panel5.BringToFront(); panel5.Visible = true; break; } }

?This didnt make a difference?

Vulpes · Answer

There's a muddle in your PanelSwitcher method as you have a combination of the 'full' and 'abbreviated' code in there. Using the abbreviated approach (which scales easier to any number of panels) it should look like it did in my previous post: private void PanelSwitcher() // no longer a timer Tick handler { foreach(Control c in this.Controls) // iterate through controls collection { if (c is Panel) { int number = int.Parse(c.Name.Substring(5 1)); // find the number of the panel 1 to 7 if (number == counter + 1) { c.BringToFront(); c.Visible = true; } else { c.Visible = false; } } } }

I added the .BringToFront and everything else ...Its switching through 4 panels now which is all I need since all I got to do is make 4 panels for each form. Now I have a with the colors of the panels 234...It only shows panel 1 and the rest are just empty. Heres the code so far...This is the only thing I need for my project to be finished then I will be working on the animation which I can do by myself lol ....Also in my program I added you in the credits since you helped out ALOT if that has any means of importance to you. private void Form4_Load(object sender EventArgs e) { btn1.Enabled = false; PanelSwitcher(); btn1.Click += btn1_Click; // back button btn2.Click += btn2_Click; // forward button } int counter = 0; int maximum = 6; // Maximum = total panels started from 0 1 2 private void btn2_Click(object sender EventArgs e) { int original = counter; counter++; //the ++ after a integer raises the value by 1 if (counter > maximum) counter = maximum; btn1.Enabled = true; // counter must be at least 1 so enable back button if (counter == maximum) //checks to see if counter is equal to that of maximum { btn2.Enabled = false; // disable forward button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void btn1_Click(object sender EventArgs e) { int original = counter; counter--; if (counter btn2.Enabled = true; // counter must be less than maximum so enable forward button if (counter == 0) { btn1.Enabled = false; // disable back button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void PanelSwitcher() // no longer a timer Tick handler { foreach (Control c in this.Controls) // iterate through controls collection { if (c is Panel) { int number = int.Parse(c.Name.Substring(5 1)); // find the number of the panel 1 to 7 c.Visible = (number == counter + 1); // make it visible if it equals (counter + 1) else invisible switch (counter) { case 0: panel1.BringToFront(); panel1.Visible = true; panel2.Visible = false; panel3.Visible = false; break; case 1: panel1.Visible = false; panel2.BringToFront(); panel2.Visible = true; panel3.Visible = false; break; case 2: panel1.Visible = false; panel2.Visible = false; panel3.BringToFront(); panel3.Visible = true; break; } } } } } }

You'll need to change the code in the PanelSwitcher method a little to accomodate the call to BringToFront: private void PanelSwitcher() // no longer a timer Tick handler { foreach(Control c in this.Controls) // iterate through controls collection { if (c is Panel) { int number = int.Parse(c.Name.Substring(5 1)); // find the number of the panel 1 to 7 if (number == counter + 1) { c.BringToFront(); c.Visible = true; } else { c.Visible = false; } } } }

Great everythings working perfectly except for my panel 3. It only goes back and forth between 1 and 2. I tried changing the maximum to 3 but that obviously didnt work lol.

Vulpes · Answer

Yes you can do that if you like but I don't recall you mentioning it before. When you have overlapping panels if you want them to retain their colors then you'll need to bring them to the top of the z-order ( the order in which overlapping controls are placed on the form). You can do this by calling the panel's BringToFront method before making it visible. For example: panel1.BringToFront(); panel1.Visible = true;

Caleb Dunn · Answer

Am I not supposed to set them overlapping each other?

Vulpes · Answer

So are you saying that you have a stack of panels rather than each one occupying its own space on the form?

Caleb Dunn · Answer

Oh srry I worded that wrong. Its only showing the first panel that its sees and all the rest behind it are the normal grey color that that forms are.

Vulpes · Answer

Do you mean that they don't show at all or that they show with the wrong color?

Caleb Dunn · Answer

Ive also been having a problem with the panels. I made all of them different colors so when they are switched I can tell if the working properly but some dont seem to show.

Vulpes · Answer

The only things that need to be changed are the maximum field and the PanelSwitcher method. Also if there's now going to be 7 panels instead of 3 then you need a way to condense the code: private void Form4_Load(object sender EventArgs e) { btn1.Enabled = false; PanelSwitcher(); btn1.Click += btn1_Click; // back button btn2.Click += btn2_Click; // forward button } int counter = 0; int maximum = 6 ; // Maximum = total panels started from 0 1 2 private void btn2_Click(object sender EventArgs e) { int original = counter; counter++; //the ++ after a integer raises the value by 1 if (counter > maximum) counter = maximum; btn1.Enabled = true; // counter must be at least 1 so enable back button if (counter == maximum) //checks to see if counter is equal to that of maximum { btn2.Enabled = false; // disable forward button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void btn1_Click(object sender EventArgs e) { int original = counter; counter--; if (counter btn2.Enabled = true; // counter must be less than maximum so enable forward button if (counter == 0) { btn1.Enabled = false; // disable back button } if (counter != original) PanelSwitcher(); // switch panel if counter has changed } private void PanelSwitcher() // no longer a timer Tick handler { foreach(Control c in this.Controls) // iterate through controls collection { if (c is Panel) { int number = int.Parse(c.Name.Substring(5 1)); // find the number of the panel 1 to 7 c.Visible = (number == counter + 1); // make it visible if it equals (counter + 1) else invisible } } }
