I have an old app still written in VB2003 that required some changes, part of that was revamping a menu that isn't behaving.I've deleted it and it doesn't show in the designer but when I start the program there it is, and still not correct.How do I really get rid of it so I can build another one?I'd hate to have to delete the whole MainMenu, this is the 5th in line, that would be a lot of re-creating.

In my card game program, I have used 4 main GroupBoxes to act as dialogue boxes. Some contain additional GroupBoxes to house such things as RadioButtons, TextBoxes and CheckBoxes.Software places them when and where needed, so I usually move them apart in the Design screen to keep them all visible at once. However, with each new GroupBox I added to the program, their behaviour became increasingly vexing.In the design window, they are not allowed to overlap, or they will either partially or completely disappear. When they disappear, I have to find them with the Properties Viewer (when selected, the 4 sizing blocks appear and I can tease the drag symbol to appear).Worse, when my program is running, a GroupBox left in the Design mode in an "unfavoured location" (for lack of a better term) will refuse to appear when called.
I have single stepped past the code that positions the GroupBox and makes it visible and I have noted that the top and left positions are correct, but when I let the mouse hover over the word 'Visible' in the line "GroupBox1.Visible = True" the popup reports it as False.There is nothing I can do at run-time to make the GroupBox appear. I must return to the Design window and try moving it to a more favourable location.
Okay so ive got this project iv been working on. Almost ready to get the beta on its way, last thing I needed to do is retrieve the EXE and change its icon. I found the EXE in the "bin" folder. Copied it to desktop. I went through the properties, no way to do it. Then I searched youtube, and google. Only possible way to change it I found was to use softwares. I tried Resource Hacker (ive used years back, this program was handy), but it didnt work. I replaced the default window-looking box icon with my icon, and that seemed fine. But once I saved and exit, the new file with updated icon was supposed to be created. Well it was, except just looking at the file icon I knew it didnt work. But when I right click and go to properties, that one changed. So why dosnt the MAIN icon change? In RH I seen no other icons
View 5 RepliesIt seems that my form refuses to draw quickly enough. I am using this

This ends with the form freezing for a moment, and then it resizes, but it's not until the end of the resize does it display properly, during the resize, their is a big black bar where the new part of the form is supposed to be.And when it's done resizing, it draws itself correctly.

In this windows forms app, I have a form with six comboboxes. Two are parents, one with a single child and the other with three children. All of these work beautifully except for one of the children. The code for each one is identical, and I've verified the query against the database a dozen times. I even have another of the children that is in the very same block of code. One works beautifully, the other one refuses to populate any data. Below is the code for the one that doesn't work. I would tell you on what line the error occurs, but it doesn't throw any errors. Try catches show nothing, and I have VS 2010 set to throw all errors, but I get nothing, just an empty combo box where there should be a list of names.

I've spent weeks working on a project. I develop on both of my computers (Desktop and Laptop) which are both equipped with VS Express 2010. The programs debug, and compile with no issues on both of my machines, even when the .exe is removed from the debug folder and placed elsewhere. However, when I try and run the program on my brother's computer, the initial form jumps up on the screen as desired. Then the program is designed to open the next form upon the click of a button. When that button is pushed, we get the following:
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I'm using Visual Studio 2005 (college only has 2005 so..) and I have a very important program to write for college.My problem is, every time I try to compile I get the error: "Error while trying to run project: Could not load file or assembly "Program" or one of its dependencies. The given assembly name or codebase was invalid." We're talking a very simple program - I've only been learning for a few weeks.
View 7 RepliesI've searched everywhere to find out why the heck my program is doing this, but couldn't find anything like it...? I'm making a flash card program. Part of my program takes images corresponding to other data from a certain area, chosen by the user, and moves them to another folder, for later use. I want to store the path for the image next to the other data, storing the path as a string. When no image is chosen, the variable for the path is simply "no image".

I have an object (ClassGPS) containing a DataTable that is exposed through the property "Satellites". My form has a bindingsource that, upon load, associates itself to a new ClassGPS object. The table has 5 columns, two of which ("PRN" and "dB") I want to chart using the new 4.0 chart tool. So the chart object's DataSource = ClassGPSBindingSource, and the DataMember = Satellites. That is all set in the designer.In ClassGPS.New(), the table is pre-loaded with 4 rows. This object is created before the form loads. When the form loads and the bindingsource is set to the created GPS object, the chart correctly updates and displays the four pre-loaded entries.On this form, I have a button that adds more entries. Tracing from the Click event, pushing the button does add the entries properly to the underlying table, and if I create a ListCHanged handler on the data source, the events are all correctly firing, but the Chart does not update to reflect the changes.
So to test, I added a Datagridview object. Just like the chart, I set its datasource to ClassGPSBindingSource, and the DataMember to Satellites. And here's where it gets weird. In the designer, the newly added DataGridView control has 4 columns in it labeled RowVersion, Row, IsNew, and IsEdit. I didn't create these columns, it does it itself. If I try to change the bindings on these columns to reflect the actual datatable names (PRN and dB) two things can happen:
1) If I hit Play (F5) to debug the program, the DataGridView looks and acts correctly inside the program and is correctly bound and updating fine as I add new data. In the designer underneath however, the changed columns have disappeared and are replaced with the original four it is creating for no apparent reason. When the debug session terminates, the columns - which just finished functioning fine in the debug session - are now gone.
2) If I hit Build, the designer destroys my columns immediately and recreates those it defaulted to.In either case, something very fishy is going on... in that the Chart, with the exact same binding settings as the datagridview, does not work but the datagridview works just fine (unless Build is hit prior to Run).Has anyone run across this? Can you reproduce it? I have bound a chart to a datatable before and it worked just fine, but it didn't have to update except when the form it was on was closed and later re-loaded.
I have a typical databound Form with a bound ComboBox bound on the form Load event.I have a typical BindingSource and BindingNavigator Control with an "AddNew" button.When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting...
mycombo.selectedindex = 0
I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to -1 As an experiment I added a button to the form and on the click event pasted "mycombo.selectedindex = 1".I added a newrecord then clicked this button and the combobox updated as expected. But I wont this to work as I'm adding a record!Is there a particular event where I should set mycombo.selectedindex = 1 apart from the two I mentioned?
Im trying to open media player (full screen) and play a movie. When i create the file path like so: Dim MoviePathVTS As String = String.Concat("""" + tempMoviePath, " \VIDEO_TS\VTS_01_1.VOB" + """")
It wont play the file but if i do it like this: Dim video1 = """F:\Movies\DvD\Angels and Deamons\VIDEO_TS\VTS_01_1.VOB"""
It plays fine? the file paths are the same including the extra "" but it just refuses to play. I need the top one because i have many movies in a treeview.
Heres my code

I'm learning VB2008 using the Express edition IDE, and would like to start using the Mercurial SCM. I have a couple of questions:
1. Should I use a single repository for all my tiny projects under C:\VB.Net\, or should I create a repository into each project [code] If using only a single repository, will Mercurial filter changes so I can see only files belonging to a given project?
2. What files/directories can I leave out of Mercury? For instance, here's what VB2008 Express created for a single-form project: [code]
3. Is it possible to avoid the empty \WindowsApplication1\ at the root of a project, so that I don't have to cd into it to find the first actual file (WindowsApplication1.sln)?
Attached is the image from an Office application, how can we emulate such?

How do I make a menu item on a menu strip link to another windows form (like a menu item that links to an about page already created in the project). I know that every coder knows how to do this, but i've read most of the instructions in the world for Visual Basic coding, but can't find ANYTHING I know coding fairly well, so I can modify it, but I can't create it my self.
View 4 RepliesI have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.
