I have my ListBox working and I'm able to select the items I want to keep. I'm trying to now get the Invert of the current selection for the items to delete.
I tried using:
if (lstLinePatterns == null) return;
for (int i = 0; i < lstLinePatterns.Items.Count; i++)
lstLinePatterns.Items[i].Selected = !lstLinePatterns.Items[i].Selected;
But
.Selected
is giving me an object error.
Is there an easy way to just inverse current selection?
Current Code:
private void btnSelectNonRvt_Click(object sender, EventArgs e)
{
// Unselects any Items to Prevent Infinite Loop
lstLinePatterns.SelectedIndex = -1;
Okay so i have everything right accept transfering the selectedindex from listbox in form1 to listbox in form2. I am using the below string item to hold the selected line of the list box, with the intent of recalling and then adding it into the form2 listbox. I get a not implemented error and i can't figure out why. I know the information is moving with the variable item, it just doesn't get printed out to the new listbox.
I'm trying to make a selection process using roulette wheel selection. To do this I created two matrix, one random probabilities and one increasing probabilities. The idea is to choose a number according to the random probabilities. Here is the code I've written.
#include <iostream> #include <conio.h> #include <cstdlib> using namespace std; int main (){ float select [5], prob [10], mat [5]; int c, r, z; cout.precision (2); cout << "Random Number:" << endl;
[Code]...
The result I got is as follows:
Random Number:
0.0013 0.56 0.19 0.81 0.59
Increasing Probabilities:
0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1
Selected Column: 0 5 6 8 9
The evaluation doesnt seem to start from c=0 again. The selected column should be 0, 5, 1, 8, 5.
I am looking for function capable of converting square matrix of integers.Where to find such function? I know the algorythm but have no time to implemnt it.
I have a visual impairment that makes it very hard for me to use the standard dark text on white background themes. I use High Contrast but many apps don't query the system for colors (I.E. aren't theme-aware) and consequently display pale or dark text on a white background regarding of the theme selected.
There is a product called ZoomText that allows for inverting the brightness of everything being displayed. I just use a normal theme, let all apps display naturally, and then invert the entire screens brightness.
But ZoomText doesn't support multiple monitors. And it does a lot more than I need. And it hogs the CPU. And it costs a lot.
Looking for some of the APIs that I need to capture the bitmaps for all monitors, invert the brightness of all pixels, and refresh the display contexts. And make that happen so smoothly that it appears like there is nothing going on behind the scenes. (DirectX, OpenGL, ???)

However, when I add to the listbox as shown above in my main form code the results all show on the same line. My understanding was that they should all be treated as separate because of foreach loop but apparently that is incorrect. I have seen mixed things online some showing that its required to use AddRange instead of Add, however, after literally hours of trying to make this work I am still coming up with nothing. I can't seem to get any code to work using the AddRange or am I finding any way to output each results on a separate line.
I need to clear a listbox from a class other than the form where it exists. Why this isn't working? I'm getting no error messages when I compile and I am seeing the Console.WriteLine text I also added in the same function. I can call this function from within my form and it behaves as expected. I tried setting the listbox to public despite the fact I wasn't getting protection level errors but that made no difference.
Just to clarify what I'm doing here... I have a form that includes a panel of user controls from another class. So there is a listbox on OtherClass and the listbox is in MyForm. Heres my code:
I am working on a Windows From application on Visual Studio 2010 where i need to use two checkedlistbox that interacts one with the other one. Let say that the first checkedlistbox is for world regions (i.e.):
Asia Africa Europe South America
And let say that the second checkedlistbox is for Countries (i.e.):
Spain Italy Romania Monaco
(all of this belongs to Europe region)
What we need to do is that when the user check on any world region it automatically checks all the countries on that region in the second checkbox, and vice versa if the users check any country on the second checkedlistbox it automatically seconds the region on the first one.
I know that is possible in Java and we know how to do it, but i don't know if C# supports this and how to do it. I was looking on the class information in the microsoft website: [URL] .... but not a concrete example on how to do it.
I have a lstYourHand that has two cards in it, I loop through the listbox to get the values of both cards. I take the string value of the listbox item (strCardVal) and use a switch to give it an integer value (intCardVal). For some reason, when I run the code, the message Box at the end gives me the value 0 as a result, it does not register me giving it a value in the switch statement. My code is below:
I'm working on creating a windows form with a listbox, textbox, and 2 buttons (add,remove). I need a way of removing every string matching the contents of the textbox from the listbox. Here's what I have:
for (int i=0;i<listBox1.Items.Count;i++) { //... listBox1.RemoveAt(i--) }
Seems to work, but I need a way to show a error message once the user clicks 'remove' and no items in the listbox match.
I was working with a richTextBox on setting its font, color and size. I found examples and got that to work. It seems like a kludge to me just to get the size set.
So, now I need to do the same for a listBox. I got the font and color set but cannot get the font size set.
The error I am getting is on line 6 below: listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;
VS 2013 Express tells me this property (font.size) is read-only. That was the same error I got on the richTextBox until I found way using the .SelectionFont structure, but the listBox doesn't support that. So, I'm stuck.
Line 8 on is working finr for the richEditBox.
DialogResult result = fontDialog.ShowDialog(); if (result == DialogResult.OK) { listBoxTopLevelChecklist.Font = fontDialog.Font; listBoxTopLevelChecklist.ForeColor = fontDialog.Color; listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;
I've changed the listbox foreground color to default application background color so I get: [URL] which is fine but when I select any element I get white background/foreground(or whatever it is): [URL]
How can I change this so I will have the same default color in the second case?
I'm making a simple airline reservation. I have two list boxes one has the section (A, B, C, etc) and the other rows (1, 2, 3, etc). I used two different arrays to put the values into the list box via form unload. The problem I can't seem to figure out is how can I update these seats and inform the user if a seat is taken or not. Lets say a customer takes A-1 (only seat taken). If I try to add someone else there it will inform me that seat is taken and to select another one. If all the seats are taken it'll tell me to put customer into the waiting list.
Also one more thing is that each row has 3 seats, so A-1, A-2, A-3 for example. If say A-1, A-2 are taken when I push a button show remain seats it should show A-3 only. I have a lot od struggle using arrays.
I have a C# WPF program that takes a SQL query and populates a column from an Oracle database into a listbox on the form. I would like to be able to compare all items populated in the listbox, and run a SQL query for each item, populating those values into a different listbox.
So far, I have this code:
string sql2 = "select unique apps.fnd_application_all_view.application_name, fnd_responsibility_vl.responsibility_name, fnd_form_functions_tl.user_function_name, fnd_form_functions.function_name, fnd_form_functions_tl.description, fnd_form_functions.type FROM fnd_compiled_menu_functions, fnd_form_functions, fnd_form_functions_tl, fnd_responsibility, fnd responsibility_vl, apps.fnd_application_all_view WHERE
[code]....
I would like to be able to basically take the "Responsibility_Name" value from the first listbox (lstResponsibilities), which is already populated, and use those values to in the "sql2" query to find the "Function_Name" and populate "Function_Name" in the second listbox (lstFunctions).
i've a function to add many buttons to TabbedPanel like is visible here
public void AddBeverageDrinkstoTabbedPanel(TabPage tp1, ListBox lst1) { food getbeverage = new food(); string[] bev_product = getbeverage.name1; FlowLayoutPanel flp1 = new FlowLayoutPanel(); flp1.Dock = DockStyle.Fill; foreach (string value in bev_product)
[code].....
What happens? When i click in any button, want add an specific text to listbox and to do this i builded an method called beverageclick(), with these code:
public void beverageclick(object sender, EventArgs e) { Button b = (Button)sender;//button sender string value = (string)b.Tag;// value = b.tag (tag of sended button tag = value (value of AddBeverageDrinkstoTabbedPanel) method)
[Code] ....
What is wrong? how can i add an specific value when an button was clicked.
program im creating that is a Mediastore. I have 3 forms one start form where you choose which form you wanna go to Lager or Kassa are the two choices. in these forms i have 1 listbox each that share the same Data. In my Listboxes i have objects of a class called produkts that consist of 3 variables Name,SerialNumber and Price. When i have added these objects to my listbox and they are showing i wanna be able to use my "go back" button to go back to my orginal form where i choose which form i wanna go to and then go to eather my Lager form or my Kassa form and the items are supposed to still there however that is not happening for some reason.
This is my second hw doing C# and I'm trying to sort my objects I have in the ListBoxes,when I remove them from the ListBox on the right then get added to the original ListBox(because when i click add it removes the item and sends them to the ListBox on the right),but when i add them the go at the end of the list and they order should matter,how can i sort the list after the were added back?

I need to take a single column and all the rows in the column from a datagridview to a listbox using a for loop. My code is giving me no errors just not showing any data in the listbox.
private void frmProject6_Load(object sender, EventArgs e) { // TODO: This line of code loads data into the 'enrollmentsDataSet.Enrollments' table. You can move, or remove it, as needed. this.enrollmentsTableAdapter.Fill(this.enrollmentsDataSet.Enrollments);
Is there a way to set the height of a listBox to show all of the items without having to kick in the vert scrollbars? I've searched on this question but can't find how to do this.
I want to kind of auto-size my listBox height to accommodate my items (within reason and perhaps set a max height which would kick in the vert scroll bars.
I tried to save some data from my listbox to the text file, but didn't work... I think I tried many combination for code but still didn't work. what to do?
FileStream fs = new FileStream("tx.txt", FileMode.Create); StreamWriter sr = new StreamWriter(fs); sr.Write(listBox1.Text); //there is that problem, but I'm not sure how to write for success sr.Close();
