How To Draw Readable Tiny Text Quickly
Jul 28, 2010
In developing a flash-based memory manager, I need to be able to view large quantities of data. With my eyes and monitor resolution, I can read hand-drawn 3x5 letters on a 4x6 matrix without too much difficulty, but none of the system TrueType fonts render optimally at that size. I've tried writing code to draw font shapes to off-screen bitmaps, and then use DrawImage to copy those bitmaps to the screen, but I can't get good performance. This is for development, not production, so performance doesn't have to be absolutely optimal, but I don't want to spend too long waiting for screens of data to refresh.
What would be the best way of either making .net display a font which is pixel-perfect what I want, or else building a bitmap out of lots of little pieces quickly? I'm using vb.net, so I can't simply generate a bitmap as a byte array and pass that to the Bitmap constructor unless someone can show me how to convert an array into an IntPtr.

I'm trying to draw a string onto the bottom of a tiny picturebox. This is done for several different scale levels, but the smallest size doesn't draw correctly. Specifically, when the PB is 16 pixels wide, I can get one digit, but not two, so numbers like 10 show up as 1. This seems like a simple case of wrapping and clipping, so I tried to turn off both. This did not appear to work. I also tried scaling the string, but that didn't appear to do anything, either. Here's the
Dim alng As New StringFormat()
alng.Alignment = StringAlignment.Center
alng.FormatFlags = (StringFormatFlags.NoWrap Or StringFormatFlags.NoClip)
Dim stringSize = grph.MeasureString(st1, mMyFont, Point.Empty, alng)
[code]....
It may have to do with passing in a rectangle for a drawing area, but if I want to have the string center aligned to that space?

Is There Any Possible Way To Convert Bytes To Readable text?

I am having trouble converting the Bytes() to a readable text.
I will be receiving packets from a UDP Connection, but due to lack of connectivity issues, they have provided me a .mem file that i am assuming is the whole stream of the packet.
So for now, i am trying to read the file and i get a collection of bytes(). but i cannot convert it to readable text.

I have a table with a column/field (type : nvarchar) that stores text. The text is read from a text file and written to the database using vb.net application.The text in the text file contains Turkish characters such as the u with 2 dots on top(in the future it will be in different languages )When I open the table, the text in the column is not readable.It converts the Turkish special character to some unreadable characters. Is there anyway to make the text readable in the table?

I want to create my special full-text index using text files, without database.I saved records ids for every word in index, in text file..Now if I want to search for tow words together; I have to get ids that is shared between these words by comparing text files of these words ids; and saving the result in other text file.[code]But now the problem if the first word has 100,000 ids and also the second word same it; the loop will take too long time! It will loop 100,000 * 100,000 times!How can I find another way to compare these files quickly; or another idea for my full-text index with text files?

I have a form which contains a large number of textboxes covering numerous panels/tab controls and I would like to have the user only have one text box visible at a given time and when the user clicks on the screen to another label with a corresponding text box I would like that to appear and the other currently open to disappear. Currently I have the following loop that goes through and changes the visibility of the appropriate controls unless it is the name of the control I am looking for:
'This is used to iterate through all the controls in the form and ensure the visibility of all other controls
' than the active control is set to false.

I want to create a tiny program that writes itself. VB.
Basically, I start it off with the smallest coding possible. Then, I want it to be able to automatically generate buttons, forms, labels by itself. I want it to compile another version of itself, and to test if it worked. I want it to in someway to be able to ask the new application if it works, and if it does to close both and to run the newer variation, then to repeat this process. I guess this is kind of like a self-manifesting application that keeps growing; an AI perhaps. Is this possible?

I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?

I have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.

I have a Socket application that, when data is received (on the Server side) and the client is recognized, the data is passed onto its own socket and stream, and the previous socket and stream is discarded.
The data is serialized with a binary formatter before sending and deserialized on receiving the data.

I'm making a front end to dvdauthor.I have a picturebox which holds the menu background. In order to draw a textbutton on the background image I store the image in a hidden picturebox. So the text doesn't get drawn to the visible background.
Dim ctl As Control
For Each c As Control In pbMenu1.Controls
If c.GetType() Is GetType(TextBtn) Then[code]...
This works the first time. But if I hit save again it writes the text to the background image on pbMenu1.
