I'm using GetFileInfo in order to get file size on movie files.
I can read good size values from files with 1.4 GB, but for files with 20GB or 32GB I get wrong values.
Is there any limitatin when using GetFileInto, or should I use a different code when using big files?
I'm quite new to VB Programming and I'm using Microsoft Visual Studio 2008 for programming. I'm writing an application that communicates with an Omron PLC via CX-Server Lite which brings some ActiveX plugins for VB. So far I solved a couple of problems and my application "is doing something" already.My question in the end might be really easy. I inserted 3 bitlamps (Omron ActiveX Components) in a form, gave them the size and position I wanted them to have. When I now start my application they show up in the wrong size. It seems as if they would keep there position but they simply have the wrong size and even overlap each others although I have them sorted nicely in Visual Studio.Another effect I have is, sometimes when I move the components around on the Form in Visual Studio they seem to be "behind" the Form. I can't see them anymore but i can highlight and move them.
View 3 RepliesI have a Windows application written in VB.NET in Visual Studio 2005.The application opens a form to perform some measurements and to present data.
The application works fine when i run it om my "development computer" in debug mode. Also when i install in and run it on my computer.
But when i install it on the customer computer and run it i get a form that is smaller in size (not as wide as in my computer) and the result is that lots of graphics components are located outside the form and therefore not availible for the user.
I am using a server report, which I am rendering in VB.net using reportviewer.serverreport.render into a PDF document.Strangely, when i do this the text in my graphs is really small compared to in the designer or when I view the report in a web browser.

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I have a label which appears full screen on a projector (VGA 2). In this label I will be sending strings. Some one liner's, some wrapped paragraphs. Some multi-line with carrage returns. My goal is to have the font dynamically change size to be as large as possible without overflowing the fixed label size.
View 10 RepliesWhats the font size real meaning? since when i use Arial font size 10 in the report its gonna take different space than the textbox im using (Both using exactly same font type/size/unit) its kinda if i set 10 milimiters to the font size why would the i and M for example have so diferent size.
i wish it was like in the Notepad where all the letters take the same space. what i need its to give a certain texbox(in the report) with auto grow to have always the same lines of height but its not posible to calculate it from vb b4 being inputed to the report.
How to make the form size automatic setting the size equals to the screen. or Maximize the whole form including the form components.

View 2 Replieswhen I click the Open button a file is opened and its items are sorted alphabetically. to do this I have doubled the size of my list. However, when I click the button again to reopen the same file, the items will ADD ON to the previous open-file event even though I have this piece of lstListboxTwo.Items.Clear()(the correct thing is to clear the previous items and add the new ones)So I think this has to do with the new size of my list..I think that I have to set the list size back to its normal size when re-clicking on the button.

I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the
size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web
(or local) fill the size of the webbrowser - almost like a mini browser if you will.

If I re-size the form, the textbox inside should be re-sized to fit the form, NOT DOCK!
Try it yourself: Plug in a USB flash drive (just a normal one with a single primary partition on it, as is the manufactures configured) to your computer.
Run WIM "Select * From Win32_DiskDrive"
Note the USB drive's size (in my case, it is a Kinston DataTraveller G3 2GB drive):
Win32_DiskDrive instance
BytesPerSector: 512

Why the partition is bigger than the disk on which the partition is created and just a part of the disk?
How do I connect the size of any button in the form to the size of the window so that it would change proportionally to the size of the window?

View 4 RepliesI'm writing a couple of custom controls in VB.Net 3.5, in VS2008, and would like to resize the font size based on the height of the control, and vice-versa. Is there any way of converting a font of say 38.25pts into a me.height, or the other way round?
I realise the font width will change dependent on the font used (which isn't an issue for my purposes), but as far as I know, the font height is usually consistent Accessibility/Large font settings won't be an issue with this application.
