Send Checkbox Items To Text File?
Apr 9, 2010
I have a checkboxlist named cblLike and I need to know how I can get all the values of the checked item and send them to a text file. I currently have other controls on the form that are being sent to a text file, so all I need to know if how to get all the values of the checkboxlist that are checked and then how to send those in the array I already have so that it will save them in the text file along with all the other values being sent.

Everything is written in codes:
vb
'CHECK IF "sIntroSequence" IS AVAILABLE IN TEXT FILE. Dim checkthevalue As String = My.Computer.FileSystem.ReadAllText("c: est.txt") If checkthevalue.Contains("sIntroSequence") Then '"INTRO SEQUENCE" STRING IS AVAILABLE. 'CHECK
[code]....
I can't seem to get the checkbox checked according to presence of a particular string in a text file. It looks like it should work but it doesn't.

Here at work we send straightup text documents to a Genicom, continuous feed, dot-matrix printer and we use the following code in Visual Fox Pro:
RUN COPY *.353+*.360+*.362+*.354+*.825+*.MSL+*.XMS+*.PQR+*.PJS+*.AJS lpt2
I'm having trouble how to accomplish the same thing: simply sending the files to the print queue.

I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.

I am looking to create a VB 2008 Express programme which converts a data stream from a picoscope muscle sensor into a power output board which controls a mechanism.In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.
So 0.8 V > = send text file (0O=100%)
0.2 V < = send text file (0O=0%)
so when muscles being senced move the device turns on and off.I think I am successfully getting the data stream from the Picoscope which is plugged in the usb. I am using codes and examples that the programming guide for the device provided.here is a quick snap shot of the code (ps2000 is the driver used for the device)
ps2000_open_unit()
ps2000_set_channel(ps2000_handle, 0, 0, 0, 1)
ps2000_run_streaming(ps2000_handle, 250, 1000, 0)[code].....
how to get the data to be displayed or how to tell the programme to do something with the data.The device also came with an example of how it can record data to an excel sheet if anyone needs the code to gain a better understanding.

I want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine. I am eager to write code correctly, not just get the code to work.
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click

I've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.
[Code]...
I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.

Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....

I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should. This is the code to send the string and my attempt at making it replace the () in the module
Module TextReplacement
Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal vKey As Int32) As Short

Dim sData() As String

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:
In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3
Selected Types 2 and 3 in CheckboxList: filteredColors
