When a MouseDown event occurs on a System.Windows.Forms.DataGridView I'm performing some action. But now I only want to perform said action if the MouseDown event occurs on any part of the Grid EXCEPT for the Headers (row or column).
View 5 Replieshow to view and populate a listview with a text file. Now I come seeking wisdom on how do create an effect based upon the location where a mousedown event occured.
Here is my example. (I like to give simple examples because it helps me learn rather than be given the answer and learn nothing).
I am working in vb.net, in a windows form. I have a map of Western Europe called picturebox1.
I want another form to pop up when a user clicks on a section of picturebox1. For example: I want a "Germany" form to pop up when the user clicks on Germany. And such for if France, Spain, Italy, Austria, England, Scotland, etc...based on the location of the mousedown event.
Historically, when working with a picturebox with sections that were rectangle, I would do little screenshots and overlay them over the picturebox and use that as a cheat.
The challenge here is that the countries are polygons and now I need to learn this for real. I am looking for a little direction on where to go to learn about a mousedown event that causes an effect based upon the location of the mousedown event.
This can be a challenge because each country is of different x, y location coordinates so I image I need to create an elaborate if or case statement to capture and evalute. However, I don't know how to acquire the coordinates of a mousedown.
I have a datagrid view with 3 columns and variable rows. I have many rows so it is tough to know what is where so, the first row consists of names.I have a textbox in which I type in a name and hit a button. Doing this, I want the location of the that cell in terms of row.no and column.no.
Extended : for the adjacent ones just add +1, +2 etc to the column number right ?
i am using an unbound datagridview so i can dynamiclly add rows. all that is working fine. but the grid is not is the location i have coded.. i am using the defualt form as a base then coding the unbound stuff in.. should i just create a blank class file and do everything? the only problem i am having is the grid must bees in the correct location according to the pixel point that i have given it. Right now it is placing the grid at point (0,0) no matter what point is entered on the line for location. so what am i missing??????

How can I find the location of my application's executable in WPF (C# or VB.Net)?
I've used this code with windows forms:
Application.ExecutablePath.ToString();
But with WPF I received this error from Visual Studio:
System.Window.Application does not contain a definition for ExecutablePath.
I am creating an application and I have the numbers 1 - 20. Each number represents a location. They are continuous. I need a way to find the closest number to a given location. For example if the event is in location 8 and there are 2 people who can attend who are in locations 6 and 10. Then zone 6 would be chosen as its closest and also the lowest. If I needed the next highest closest number then I could pull all of the numbers into an array and sort them and then pull out the one which is the next highest zone. However as I need to find the closest number which could be lower, im not sure how to achieve this.

I am trying to write a simple Visual Basic 2008 installer that copies word macro templates to Word's startup directory. On Vista and 7, that directory is the user's AppDataRoamingMicrosoftWordSTARTUP directory. Is there a way that I can programmatically find this directory? I.e. is it safe to say that this directory will almost always be in this location such that I can simply get the user's home directory and then add AppDataetc.... or is there a registry or something else that I can access to get Word's current standard startup directory?
View 1 RepliesHow can I efficiently find the location of the first instance of a four byte sequence within a byte array? Is there something more efficient than looping through the whole array, or a built-in method?
I'm searching through a byte array for a pair of CrLF. I can't convert it to string for an InStr first because I need the position of it in the original byte array.
I am trying to figure out the location of this, as it delimits between a string portion and a binary portion, similar (well, exactly like for this part of it) to an HTTP header. There is a string portion, and two CrLf before the content begins.
So I have a string that I need to search through for certain strings. If they exist, then copy that string to a text box. There has to be an easier way to do this then what I have below

What is the best and fastest way to find the exact location(Drive/Folder) of a specific file, without scanning the whole drive. Right now, I am using those two instructions to locate EXCEL.EXE so I can properly call it with a shell command.[code]It is quite a long process, and I have to deal with some access denied folder like System Volume Information. I am quite new to VB programming.

How can I get the screen coordinates of the RowHeader? The code below does not display the form in the proper location. I want the top-left corner of the form to be displayed 15 points to the right of the Right property and 15 points below the Bottom property of the RowHeader.

In vb6 when you wanted to alter the effect of a mouse click, you could use the mouse down event and alternate the action depending on the value of the shift, control and alternate key. (and also detecting if the right or left mouse button was clicked)
When trying these in my project, I couldn't find the right codes to do this. I can't imagine this feature isn't available so I'm sure I am just messing up somehow.
Im currently writing a program to control a Velleman k8055 usb interface, i started by assigning keyDown and Keysup to control outputs. this worked fine, now ive added buttons to control the same outputs with MouseDown and Mouseup. however when i start to debug, the mouseup and mousedown works fine, but not the keys? is there a special code to use them with one another.
Heres some of the codes for each..
Private Sub Button1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Button1.KeyUp
If e.KeyCode = Keys.I Then

Another little problem.I have a form with a control (Picturebox or perhaps flash) which uses graphic hotspots instead of controls with handles so when the control receives a mouseclick, it does different things depending on the coordinates of the click.I can obtain the handle for the main control and can see where the hotspots are as they look like buttons and set a point to that location.How can I send a mouseclick (WM_Mousedown?) to the precise point on the control?If I'm not mistaken, using Sendmessage with BM_Click would tell the control it was clicked but without coordinates.I'm trying to do this using Visual Basic from Visual Studio 2008
View 6 RepliesI make 3 datagridview control in 3 tabpages with same size and location, they stack together.I can tick the related datagridview to show such each datagiridview.But when initialize or tab selectedIndex change event, change from dgv to another dgv. dgv display in mess, all border line and color are not shown property.When I resize my main form cause dgv resize, it display fine.
1)Is it bugs for dgv ?
2)I try to run the Main_resize before but also not ok , need to manually regulate the main form size. [code]
Is it possible to handle a mouseDown event in VB.Net (2008) regardless of the control firing the mouseDown event? Basically, I just want to catch a mouseDown event at the "form level" and don't want to program mouseDown event handlers in every control. Is there a way to do this?
View 2 RepliesDuring a MouseDown event, I issue a DoDragDrop. In the subsequent DragDrop event, I call a DLL to update a Ms-Access database. The SQL is in error so there is an exception. I can catch the exception in the DLL but not in the MouseDown event. Stangely without any try block, stepping over the ExecuteNonQuery() returns me to the line next to the DoDragDrop without the debugger stopping on the exception. In release mode, the exception is completely ignored. There are posts talking about event being "indirect" but I dont understand.
View 3 RepliesI would love some help on how to get a DataGridView's Row & Column location on a mouse double click. My program requires that I dynamically add n-number of tabpages with DGV's so I declare my own class that inherits TabPages and creates its own DGV control.
For the code below I use a simple form (form1), add a tabcontrol via the forms designer (tabcontrol1) to it and remove the two default tabpages keeping the basic tabcontrol.

I have a context menu which is shown over a DataGridView as follows below. The Context menu is shown if the mouse up occurs over the second column of the DataGridView. I also have a bunch of event handlers set up for each item in the context menu. I now want to pass the location of the cell in the datagridview to the event handlers.Do I have to pass the NewPoint() to a public variable and then translate that into a cell location within the event handler?
