I'm currently working on multi selection on the Picturebox. I'm kinda of stuck with these coding.
Public Class Page_2
' for selection on part of body
Private start As Point = Point.Empty
[code]....
Currently I'm trying to make multi selection (draw shape) on the picturebox but no matter how i edit my code, it jus dn draw any square or circle when I click on my button (either circle or square).
Below are the codes that i'm currently working on:
Public Class Page_2
Public blnCircleClicked As Boolean 'Is The Circle Tool Clicked?
Public blnSquareClicked As Boolean 'Is The Square Tool Clicked?
[Code]......
I have a listbox (20 Items) with multiselection and label that disply the selection and one button. So I wrote (it works fine)
[code]...
Now when I click on button the label show lets say Item2,Item5,Item10,How do I take off the last ","
somthing like that Item2,Item5,Item10
I used to do: Dim s As String = Trim(Label1.Text)Label1.Text = s.Substring(0, s.Length - 1) but it give me an error converting intiger to string
[code]...
now I wanna know how to make multi selection each time
I am creating a Windows Form exe using VB2008. The documentation for VB2008 says "Multi-selection is not supported on CheckedListBox". But it works very well in debug mode. I cannot change the properties of the control in the IDE but I can run the following statement (clbProj is a CheckedListBox control) in the load event and it implements the multi-selection on the control.
clbProj.SelectionMode = SelectionMode.MultiSimple
I run many tests in debug mode with this option and it works every time. The program processes every checked item in the list and works as expected.
However, when I compile the program and start the exe, it throws an error saying "Multi-selection is not supported on CheckedListBox".

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..

It worked. But, when i click on the next student and go back to the previous, the picture is not there. When I stop the debugging and start again the picture is there but it stops displaying again after going back and forward.
whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)

View 1 RepliesI want to retrieve all input, select and textarea fields only and possibly change their data value. I currently declare as: Dim theElementCollection AsHtmlElementCollection = WebBrowser1.Document.All ' which I then iterate through and select on tag name.
I would like to be more efficient and do something like: Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("input", "select", "textarea") but GetElementsByTagName doesn't appear to support multiple selections. I saw on the net where someone declared as Dim Tags As HtmlNodeCollection = docNode.SelectNodes("//input | //select | //textarea") I tried this but HTMLNodeCollection is not referenceable under HtmlDocument. I have played around a bit and can't see an equivalent.

View 6 RepliesWanted users to choose two options 1.(tick) 2 blank text so they can write things.
Was thinkin how this can be achieved using a comboBox. ?
ok, got a question here, two really. first i'll ask the hard one, as i think i have my other one out of the way so i'll save it for later but i made a program where a user enters in dimensions in several text boxes in inches. there are radio boxes that the user decides what thickness of wood they would like to use. what i'd like to do is add metric into the program and use two combo boxes. one combo box drops down and you can select inches, centimeters, or millimeters. the other one drops down to choose the thickness of the wood.ok now here's my question. say i pick inches in the first combo box, i'd like the second one to display only the thickness of the wood in inches, no metric. if i pick centimeters, i'd like the second combo box to display the thickness of the wood in only centimeters, no millimeters or inches. and the same goes for millimeters.i also have the program on a timer that runs at 100 milliseconds so the user can quickly see the differences in dimensions they put in instead of having to hit the calculate button over and over and over (not sure if that really matters or not, had a couple issues with the boxes earlier but don't think it was timer related now)but is this possible? basically just looking for the kinds of drop boxes that you see on a page like autotrader.com where you select dodge, and then only the dodge cars are listed, select chevy and the chevy cars are listed, etc.
View 7 RepliesI use vb2010 to create a simple windows form.I have a checkedcombobox which gets its items from a column (titles) from a .mdb database (this works). When I check an item or multiple items in the combobox, I want to display (multiple columns) the title and for example info in a datagridview.

Background: ok I have an app that hides in the system tray. During its operations in the background it can try to invoke an outside app several times.. and I need to track when the call errors out.. I was using messagebox's but for some reason if the app hidden the messagebox's dont come up and goto the forefront. So in reading about this I read I should just use a form to do it.. so I did.. works fine.. well works fine for one error.. but if the user tries to do 3 of the same operation.. and lets say first errors.. second works and third fails.. using one error form wont work.. since I diaplay the error one.. then need to display error 2.. I need 2 error forms so they can click OK on both.[code]...
View 2 RepliesOk, Im having trouble passing a value from one form back to another using a listbox... The user clicks a button in the main form to bring up an instance of another form (form2.show). In that form, the user then then selects a number 1-5 and then presses done:
Code:
Private Sub frmPlayer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
If lboNumber.Items.Count = 0 Then 'list box is empty
For x = 1 To 5
[Code]...
How do I pass that value back to the main form as a value when the user clicks done?
How would I display list items from multiple selection listbox in order they are clicked?
View 4 RepliesI am creating a document control system for standard operating procedures (SOP) in MS Access 2007. I have just started an online VBA class and have moderate MS Access 2007 experience. This thread is very detailed and lengthy.I have the tables set up and forms created for CREATE, SUPPLEMENT etc. I need to create a user interface so that when they open the database it pulls up a form that has buttons for "Start New SOP Process" and "Modify Existing SOP Process". Every step of writing an SOP is dated so that management can have outputs for target measures (to see why it takes so LONG to write an SOP from start to finish). After the user selects "Start New SOP Process" or "Modify Existing SOP Process" I am trying to have a Combobox appear with a drop down box of change types: CREATE, SUPPLEMENT, and REVISE.
Primary Key Explanation:Each document has a 3-part number comprising a 3-part PK. 1.001v1.0. Where 1 is (1-6) identifying what type of SOP: Document Type,.001 is the Document Series (a sequential number for each type of equipment--the 2nd SOP written for a document type 1 would be 1.002v1.0) and v1.0 is the version.
For example, lets say Document Type 2 indicates field equipment. The very first SOP written for a piece of field equipment would be 2.001v1.0. If a supplement is made to the SOP for that same piece of field equipment, then it becomes 2.001v1.1, if a revision is made to that same piece of equipment it becomes 2.002v1.0. If we buy a new piece of field equipment it would be assigned SOP document number 2.003v1.0.
After a document is changed (any part of the 3-part number is changed) the previous record is put into an archive table so that the technicians/general public have access only to the most recent version of each SOP. I am going to store them on Sharepoint with an Archive Folder and an Active Publications Folder and a link to the document is provided in the database. However, while a document is being modified (going through the SOP process of reviews and drafts) the users are going to need access to the previous version until the most recent version is approved (maybe I could have the document be archived upon completion of the Document Link control).
For each Combobox option I need a different "On Click" command to open the associated forms for each "Change Type". I have the necessary forms already grouped (using subforms and tabs) for each change type: CREATE SOP (has all of the forms needed when creating an sop), SUPPLEMENT SOP (has all forms needed when supplementing an sop), REVISE SOP (all forms for revising). I am trying to use If Then statements for this...
The modify part is the simplest. I think the Combobox for the "Modify Existing SOP Process" should consist of "Change Type" (CREATE, SUPPLEMENT, REVISE), "Document Type", "Document Series", and "Document Version". I want the "Change Type" to open up the correct group of forms with "Document Type", "Document Series", and "Document Version" finding the existing record that needs to be modified (i.e. so that the user can add dates for completed activities as the SOP process progresses: draft revisions, reviews).
The "Start New Process" is even more complicated. Each change type does more unique event procedures than just opening the forms (which I can't even figure out to begin with!!). The Combobox would still be "Change Type" (CREATE, SUPPLEMENT, REVISE), "Document Type", "Document Series", and "Document Version". However the following is what I am trying to do for each "Change Type":
When "Create" is chosen from the Combobox it will find the next record in the document series by the user selecting the correct "Document Type". I would like to add a formula so that it adds .001 to the previous record (giving the next sequential number), and force v1.0 to be entered and not able to be modified, since a newly created document can only be version v1.0. Then it would open the "CREATE SOP" form (all forms associated with "Create" compiled on one form by tabs and subforms--I already have this complete for each "Change Type") and require the user to fill out all document information controls (title, description, etc) before closing.
When "Supplement" is chosen from the Combobox it will find the most recent record by the user's input of Document Type and Document Series. I would like to add a formula so that it adds .1 to the previous Document Version. Then it would open the "SUPPLEMENT SOP" form. It would be useful if the fields for the document information controls (title, description, etc) were appended to this form but it is not necessary.When "Revise" is chosen from the Combobox it will find the most recent record by the user's input of "Document Type" and "Document Series". I would like to add a formula so that it adds 1 to the previous Document Version and forces the decimal value to be 0 (revise and create change types have to end in a "0"). Then it would open the "REVISE SOP" form. It would be useful if the fields for the document information controls (title, description, etc) were appended to this form but it is not necessary.Additional buttons I would like to have on the Main Menu Form--opened when the database is opened (includes "Start New SOP Process" and "Modify Existing SOP Process") would be:
"View All Publications" where a user can not edit anything, just gives them access to the current "active" SOP links. It would be a complete list of all of our SOPs. I think I could use a query "Retire" which would put an SOP into the Archive table/folder on Sharepoint. This would be useful in addition to the automated retiring of previous version in case we discontinue use completely of a peice of equipment or administrative procedures (yes we have SOPs for EVERYTHING!!)"Target Outputs" which would be a report showing the timeline of the SOP process so that management can see where we are spending too much time (my vote is for the design of the document control system!!)"Maintenance History" which would show all previous versions for each piece of equipment and administrative procedure."List of Archived SOPs"which would show all of our inactive SOPs, for the Quality Analysis/Quality Control person's benefit.
I had set the multiselect option to true for listbox.Let me know how to move the list items up and down with this option.
View 2 RepliesI'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).
So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.
I have been given the task of making a small program in vb.net to have two list boxes. The first list box contains the data and the second one is blank, when you select the one bit of data from the first list box it can be dragged and dropped into the other list box. my task is to make it so you can select multiple bits of data from the first list box and all that is selected is draged over to the second one when you drag and drop it.
View 1 RepliesI'm trying to dive into what I consider a deeper end of VB.net to see how far I can go with it. I have a project created, ironically called "My First Server". The aim of this is to create a server which can handle multi clients but additionally isn't the commonly shown tutorial setup of a console application. So it is created as a Windows Form application. The main form (Public Class PrimaryForm) consists of only one control which is a listbox control. This is named LogOutput.

I am currently working on a project for school in which I am trying to implement a multi user login on one of my forms. I have an internal database connected in which one of my tables contains the user-names and passwords. I have a For/each loop to search the table for a matching username/password before allowing access to next form. The problem is even if the username/password is correct, my message box still appears to notify of invalid credentials, but still allows access to other form. The problem only occurs when I implement two For/each loops. With one, code works fine. Can any one see what might be wrong?
