Create A Tiny Program That Writes Itself?
Oct 30, 2011
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 was just wondering if it's possible to create an app that interacts with a database hosted on a web server... or is it only possible using VB.NET? Also if it is possible, is there any good documentation or tutorials I could reference?

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?

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 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?

Im trying to buffer data being written to a device on a com port. The equipment attached to it does not use any form of flow contol and if you write to much information to quickly it falls over. So I have had the following thoughts.
I would create a list of strings and when I wanted to write data to the com Port I would just add the string to the list. I would then have a Sub running its own thread to step through the list, write the string to the com port ,pause a fixed amount of time, remove string from list and repeat until the list is empty. Then keep looping the above.
Code I have so far is below
Private MsgList as new List (of string)
Private sub MsgPump ()
Do
[Code]....
THis does work but If I add strings to MsgList to quickly it throws an exception.

I am needing to write to a "rtf" file, and always insert my text on line 3 of either a new or an existing rtf document.I'm familiar with vb, but have not done much with the system.io functions. I have been testing several examples from the internet using the streamreader and streamwriter but still having issues finding a way to "insert text" on a specified line number. My questions:
1)I will always need to write on line #3, do I need to read all lines as this example shows "lines.AddRange(System.IO.File.ReadAllLines("C :/test/myrtffile.rtf"))"

trying to write to c:windowssystem32 on a windows 7 x64 machine, but the application keeps writing to c:windowssyswow64 instead. I have heard of windows interpreting commands and modifying them to be what microsoft "thinks" you are trying to do.when dealing with 32 bit apps running on a 64 bit os.the line of code im using is:
System.IO.File.WriteAllBytes("C:WindowsSystem32dbcon9x64TEST.dll", My.Resources.dbcon9X64)
the issue is I need to write files to both c:windowssystem32 and c:windowssyswow64 ....the files need to have the same name.

My application writes to the event log if there is an error or other status updates.
The application checks to see if there is an event source named "applicationName"and if not, it creates the source (see code below).
This works fine if the user is an administrator.
If the user is not an administrator, an error is thrown when SourceExists is called:
{"The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security."}
In my environment, the typical user is NOT an admin. Therefore, I cannot use the event log in my application.
Is there a way around this, or is the event log effectively useless for distributed applications?

I have a program that currently takes data and writes it to a MS Excel spreadsheet. (automatically opens the program, creates the cells, and fills them with data)
I would like to add an additional feature to my program that offers support for OpenOffice.org's 'Calc' spreadsheet program. (so users without MS Excel can use the application) So I am basically asking if anyone knows how to automate OpenOffice 'Calc' from VB.net. (I am using Visual Studio 2005)
I have searched on the OpenOffice forums but no one seems to know the vb.net code for this. So I was wondering if anyone here has done this, or would know how to do this.

how can I let VB.Net writes an excel 2007 file? For example, the data in a TextBox will be written to the excel file every 30 seconds.The enviroment is VS2008, .Net 3.5.I've just started VB for one month, so please give me a piece of code to help me understand. I tried to find the solution on the Internet, but none of the codes worked for me, some people mentioned import "Microsoft.Office.Interop" in the code, but if do that in my code, VS said that "Namespace or type in the Imports 'Microsoft.Office.Interop' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

I am writing an app that reads from the com port, filters the data, then writes to the text box, then immediately starts over. This all takes place in an endless " do while" loop within the "start" button code. I also have a end button too which closes the com port and ends the program. Some other buttons are present also to change the filter settings.Problem is when I click start, data is logged, but none of the other buttons work. Also some of the text boxes are "see through" and dont look like thy have updated with the rest of the form.
