I'm using winforms and I want to set a checkbox on a dropdown menu item, but I don't know how to access the dropdown menu items.
I know ToolStripMenuItem items are attached to ContextMenuStrip items but I'm not sure how to navigate into the ToolStripMenuItem section to read/set those menu items.
ToolStripMenuItem listbox_font_size;
cmsListBox = new ContextMenuStrip();
cmsListBox.Items.Clear();

I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
I'm having issues with drawing a flat style dropdown menu in XP.
Here is the custom dropdown menu element:
public class FlattenCombo : ComboBox {
private Brush BorderBrush = new SolidBrush(SystemColors.WindowFrame);
private Brush ArrowBrush = new SolidBrush(SystemColors.ControlText);
private Brush DropButtonBrush = new SolidBrush(SystemColors.Control);
public Color HighlightColor { get; set; }

Here is what it looks like in XP:
And here's what it should look like (this is how it's rendered in Windows Vista/7):
My project is to make a options menu for the user to select a shape and than draw out the shape. That whole process is already done and ready to go. What i am having trouble on is totaling the number of selected shapes. For example, at the end of the program i need to prompt a message saying ("You have selected "shape" this many times "number").
View 1 Replies View RelatedMy problem is ToolTips are not shown if any of the tool-bar menu items is disabled/inactive.
They are shown when all tool bar menus are active/enabled.
I am using TTS_ALWAYSTIP while creating Tool-Bar.
What to do to enable/display tool-tips always.
I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
I cannot check the checkbox in my datagridview.
Here is my code.
First, I added a checkbox column.
private void addCheckBoxColumn() {
DataGridViewCheckBoxColumn checkColumn = new DataGridViewCheckBoxColumn();
checkColumn.Name = "clmCheck";
checkColumn.HeaderText = "";
checkColumn.Width = 100;
checkColumn.ReadOnly = false;
dgv1.Columns.Add(checkC

Ok so I'm working with a windows form in C# and sql server database. I'm trying to do something like what is in the image below using a datagridview. My question is how do I 1) ensure only 1 checkbox is checked per row 2) do math that 'links' a checkbox column with another column, and add the totals. I understand that asp.net and web forms would be easier but we have not reached that point in the course yet. Would this be on the right track:
foreach (DataGridViewRow row in dataGridView.Rows)
{
if ((bool)(row.Cells["Checkbox"]).Value || (CheckState)row.Cells["Checkbox"].Value == CheckState.Checked)
{
// Do something
}
}

This is what I have so far, it gives me a nice menu to select from and it all works but after I make a selection it closes the program. I tried to return to it but it won't work for me
#include <stdio.h>
int main() {
int choice;
int deposit;
int balance = 500; {
printf(" CHOOSE FROM THE FOLLOWING

Im trying to Uncheck a Checkbox control with following code.
Code:
else if((point.x >= (rcRememPass.left - 4) && point.x <= rcRememPass.right) && (point.y >= rcRememPass.top && point.y <= rcRememPass.bottom))
{
if(m_CheckBoxRemem.GetState() == BST_CHECKED)
m_CheckBoxRemem.SetCheck(0);
else
m_CheckBoxRemem.SetCheck(1);
}
Above code snippet is from OnLButtonUp(). Whereas else part working good why the if part is failing to uncheck the box ?.
I'm trying to find a way to call a variable checkbox.
i.e.
for (i = 10; i < 20; i++) {
Checkbox[i]->Caption = Some Database Information
};
Note: Checkboxes are all called Checkbox10 ~ Checkbox19
I want to send messege to click select check box. I can click button but I don't know how to select check box with VC.
View 2 Replies View RelatedI'm having issues with selecting the next item in sequence in a combobox dropdown. The dropdown consists of letters A-Z and there is a timer that I have running to change the letter every x minutes. What I need to do is if, for example, letter A is selected, when the timer goes off, it will change to letter B, etc. If it's at letter Z, it needs to go back to the first item, letter A.
letterCode.SelectedIndex = letterCode.SelectedIndex + 1;
if (letterCode.SelectedIndex >= 26)
{
letterCode.SelectedIndex += 0;
}
I have the above, but I keep getting an error:
InvalidArgument=Value of '26' is not valid for 'SelectedIndex'.
how to get this working (letter changing logic block).

I am working on a paint program (already quite well developed) and I have a 'Resize' option in my Menu. When pressed it activates a custom dialog for resizing the image with 2 numeric up/downs to adjust width and height. It all works perfectly. But I want to include an 'Aspect Lock' checkBox like a professional program would have. It should immediately change both values as you adjust either one.
Here's where I am totally stumped! Of course I have tried and tried various codes, but nothing works properly. My values jump erratically or won't change at all. I wonder if trying to change the value of one numeric up/down while inside the code block for changing the value of the other one has got them screwing with each other somehow. Any example code that could accomplish what I'm trying to do?
I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.
I have created a form (in ASP.NET and C#) which have 5 dropdown
1.3rd dropdown fill on the basis of 1st n 2nd dropdown value
2.5th dropdown fill on the basis of 4th dropdown value
I applied onselectedindexchanged event on 2nd and 4th dropdown and both are autopostback true.All values come according to the requirement.
Problem is when I select a value in 3rd dropdown and it becoming change when I select some value from 4th dropdown.
passing selected row in gridview to my dropdown. I have 1 gridview, 1 textbox and 1 dropdown list box. My dropdown is populated by SqlDataSource from my table Country. On my gridview, I have 3 columns, which are SELECT, NAME and COUNTRY. Under SELECT column, I have my hyperlinked Select, every time I clicked on a certain row NAME will pass in textbox (no problem with that), but in my dropdown it does not populates the COUNTRY that I choose. For example, I have Jack for name and USA for country. Beside Jack and USA, I have a hyperlink Select, when I click Select, Jack will display on my textbox and supposed to be USA will display on my dropdown but not displaying instead it says an error "'cboCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have tried the codes below:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
txtname.Text = GridView2.SelectedRow.Cells[1].Text;
cboCountry.Text = GridView2.SelectedRow.Cells[2].Text;
}
Only the textbox os working, no luck at all in dropdown...I'm using c# and asp.net.
I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
Code:
void CDummyView::OnUpdateMenuItem1(CCmdUI* pCmdUI)
{
if(m_bShowMenuItem1) {
pCmdUI->Enable(TRUE);

I do some research about getting the coordinates from the list items but without success. I would like to make that when i press down my mouse button that little blocks fall "out" my mouse and stack on top of eachother.

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.
