Set The List Size Back To Normal Once Have Doubled Its Size (arrays)?
Jul 16, 2009
when 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.
Public Class frmForm
Dim List() As String = {""}
Dim count As Integer
I am working with vb.net and want to increase the size of image when the cursor is over that image, but the image should come back to its original size when the cursor leaves that image area.I've used the following code to increase the size of image:[code]I've used the default size class but, it gives some different dimensions.by the code that brings the image into its original size that I've been declared into the picture box properties.
My users uploads a picture and the picture get saved into my SQl Server Database.My users view the picture on the page in a normal Image WebControl with size 150px by 150px - example can be found[url]...
If the user uploads a picture of 300px by 200px the image will look funny in my static 150px by 150px Image box. Any idea how i can display the Image so it wont be fuzzy?
Also, how can a have some form of pop-up that will appear on the screen, showing the actual size of the picture from the database when the user clicks on the 150px by 150px Image.
Note: I dont want the Image static size to increase as this will totally mess up my page layout and look. It must be some form of pop-up or something. Something i have seen before i think was really cool. User clicked on the small image and then a pop-up appeared in the middle of the screen with the actual size of the picure and everything ells on the page was disabled until the user clicked on the close button.
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.
being used to PHP and the easiness of creating arrays with no specific size... I'm hating arrays in VB.
Is there a way I can create an array who's size I won't know?
I'm pulling information out of an XML file and need the information available in another sub - so I'm stashing it in a public array I create at the beginning of the form.
I have added a Split container onto my Form and within bottom Panel I have added a list box.How can I increase the size of the list box as I increase the size of the panel?
i am in the process of learning myself VB.net (2010 dotnet 4 )And am a litte confused in whats the best way to program what can be called an array.i want to have an array that looks like this,
{{"aap", 1}, {"noot", 2}, {"mies", 3, "boom"}, {"vuur", 4, 7}} now i tried to declare
Working with System.Cryptography, I'm noticing that data arrays up to a certain size will either conform to the size of the Initialization Vector (IV) or the size of the Key provided. So with a 48-byte Key and a 32-byte IV, up to around 42 bytes of data will encrypt to 32 bytes and 44+ will encrypt to 48 bytes of data. I've tested this with a variety of data arrays, and it seems to always come out the same... but I have a concern that higher byte values in the original array may result in longer encrypted arrays.
how or whether I can construct byte arrays that will be guaranteed to come out of Encryption at a pre-determined size?
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.
Whats 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.
Im trying to resize a picturebox dynamically using .size.height and .size.width Its not working. This is the error message: "Expression is a value and therefore cannot be the target of an assignment." Never used height and width before. Been trying to find the answer, but it seems beyond me. Im sure its easy. Anyone know whats wrong with this?
I had set a print format to print some word in a Text box, when I input the text in text box is an normal size from system,but I want it print out to printer follow the Rectangle size that is was set to print out on paper.actuary i want it can auto size the font size follow by the length of string.
I'm new to VB in Visual Studio 2008 and am just trying out some simple test.I just want to change the Font & Boldness of some text but get the following errorProperty 'Size' is Read onlyI have been browsing the forums and it seems that changing the font size etc isn't as simple as
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.
I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all.I also need a regular expression to go the other way as well.To elaborate below is an example of the conversion I am looking for:
<font size="10">some text</font>
To then become:
<span style="font-size:10px;">some text</span>
So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end).The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both:
I also need another regular expression to do the opposite conversion. So for example:
<span style="font-size:10px;">some text</span>
Will become:
<font size="10">some text</font>
As before converting the tag but this time removing the "px", I don't need to worry about changing the font size.Again this will also need to cope with the size styling, font styling, and a combination of both:
I am extracting basic HTML & text from CDATA tags in an XML file and then displaying them on a web-page.The text also appears in a rich-text editor so it can be edited/translated, and then saved back into a new XML file. The XML is then going to be read by a flash file, hence the need to use old-fashioned HTML.
The reason I want to convert this code is mainly for display purposes. In order to show the text sizes correctly and for it to work with my rich text editor they need to be converted to XHTML/inline CSS. The rich text editor will also generate XHTML/inline CSS that I need to convert 'back' to standard HTML before it is saved in the XML file.I know the temptation will be to tell me a number of different ways to set up my code to do what I want but there are so many other permutations I haven't even mentioned which have forced me down this route, so literally all I want to do is convert a string containing standard HTML to XHTML/inline CSS, and then the same but the other way round.
im toying with an idea based round having controls end user movable at runtime, and having a function to save the current position/location of all the controls, so then i can skip through presets i already made as it were. Ill be using .ini files eventually (just testing with txt files to check it was a valid aproach) I can get all the info i need into the txt file, the problem is how to read it back into the app?
Okay here's what I'm trying to do. I want to change the font size of a label based on the size of the form.If the form size is 0 through let's say 500 I want the label size to be 50. How can I write this?
If I have form say sized 1300 x 800, I would like to proportionally size the form to the computers screen size. I can get it to size to the screen size, but it is not proportional
I developed a form application on my computer, but when it was used in another computer with different screen size, i was told the form didn't fit. Do I have to adjust the form size or any other ways to let the form compatible on different screen size? (could be different screen size or wide screen)
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
Caption: Kingston DataTraveler G3 USB Device
[CODE]....
Why the partition is bigger than the disk on which the partition is created and just a part of the disk?
I am after a property that makes a control (textbox, datagrid or other) move according to the forms size. Because some of the controls I got does that, and I really don't want it. I've been looking at them but could not find it
I'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.
I am trying to split the image into 9 equal regions , and the below code does it well the problem is i want to get the selected image size and not picturebox sizeso what should i change to get the selected image size instead of picture box sizei dont want the picture box to grow in size with image because it will hide other buttons/textboxes etc
Dim xi As Integer = (PictureBox1.Image.Height) Dim yi As Integer = PictureBox1.Image.Width Dim px As Integer = xi / 3
i've been coding a sidebar but i dont know how to make the size to aoutomatically fix the screen size..i mean if the screen resolution is 1000x789 or 890x678 s stilll fit to it I have find in google and youtube but still i didn't get any ides on how to do it And also if possible can we code s sidebar that automaticcally hide when we did not move our mouse to it?
