I get a task: to color the control scrollbar (a gridctrl scrollbar, whatever). In the first attempting I didn't succeded ... So, I started to trying coloring a CListBox scrollbar ... I developed a derived CListBox where I override OnCtlColor:
I'm have a bitmap that's about 4000x2000. But I want to put it all into a picture control. I attempted to use stretchBlt() to shrink it. But it did not work.
Code:
HBITMAP originalImage = CreateDIBitmap(m_picture1.GetDC()->m_hDC, m_bmiHeader, CBM_INIT, (unsigned short *)m_OriginalBits,
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 } } Attached image(s)
In a MDI-app with some toolbars and statusbar I created also a controlbar which can be docked to the left side. My problem now: how do I get the exact height of the controlbar?
In CalcDynamicLayout I set the height for the docked state to the height of the mainframe. This value is too big, but it will work basically.
But how can I get the exact height of the controlbar?
I'm writing an ActiveX control. In one of the functions I'd like the user to be able to pass me a pointer to a buffer that they created which I can then fill with data and return a success/error code. What's the appropriate way to do this? I was thinking about just using an OLE_HANDLE type for the parameter and then casting that to pointer inside the OCX but I'm not sure if that's safe or the right way to do it.
I am using a slider control on a dialog box. I have handled OnLButtonDown for Slider control. But I wonder its not getting called whenever I click on the slider thumb, instead it gets called when I click anywhere on the dialog.
I want to handle OnLButtonDown when I click on the slider thumb.
When I create a list control I can assign an image list to it with the ListView_SetImageList().
By default, when just created there is no image list assigned as can be checked with ListView_GetImageList().
Now, what should happen when I do following call:
Create list control. Create an image list Get the current image list Assign an image list to list control Display some items Assign an old image list to list control.
Does strings on the list control should be indented?
Here is an imgur link to my current homework. [URL] .....
As you can see on there I have them listed on which ones are supposed to be sentinel and which ones are supposed to be count control loops. This is currently what I have:
Code: #include <iostream> #include <cmath> #include <iomanip> #include <fstream> using namespace std; void main() { int count = 0; int sum = 0;
[Code] ....
This class has me stumped currently and I am having a hard time breezing through the class at my instructors speed. So I don't want to get too far behind.
Right now this program is giving me an error that opens CMD and gives me infinite lines of "0's".
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();
1. Using a CScrollView as the View class type. 2. Using Document/View Architecture. 3. Insert multiple Common Controls such as CEdit, CButton, CListCtrl into the View dynamically. 4. All the Common Controls is base on a template created by user. So I do not know the quantity of the Common Controls.
This is the plan on how to do it:
1. In View OnInitialUpdate(), read the template to get all necessary info on the Common Controls to be create. 2. In View OnInitialUpdate(), create all Common Control. Some Common Control may not have WS_VISIBLE as it may not needed at initial stage. 3. In View OnUpdate(), I need to refresh the Common Control properties such as is its text, position or its visibility. This should happen if Document call UpdateAllView().
My Question: 1. Is this a normal & useable plan? 2. Do I miss other functions for any other messages? 3. Still wondering if I need to involve any coding in OnDraw() for this plan.
How would I go about selecting a subitem in a listview control with just pure Win32 API? I know it's possible with MFC... but I can't use MFC for this project. Right now, when you click on a subitem , it selects only the first column of the row . I used the following by referring internet. But its not working.
HTML Code: iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED|LVNI_SELECTED); ListView_SetItemState(hList,iSlected,LVIS_FOCUSED|LVIS_SELECTED,0x000F);
I have a tabbed dialog with a couple of Separate dialogs. I created classes of CDialog for each dialog. Im trying to get the text from the edit control from the tabbed dialog and it appears in a message box when I press a button on the main dialog.
Code: myDialog test; test.UpdateData(TRUE); CString bla = test.m_edit1; test.UpdateData(FALSE); MessageBox(bla,bla,MB_OK);
The m_edit is a variable of CString for the edit box
it gives me a error and crashes.
How do I get the text from the other dialogs edit control?
I want to show a list of graphical items in 1 or 2 columns (user selected). I will draw the items (owner-draw). I tried many hours today to find a solution with clistctrl. Is it possible to make it with clistctrl?
