Is there a possibillity to get in a vb program information from a called vb program?For example: Dim id As Integer = Shell("C:program.exe id_1") program.exe is a vb windows form program and must return a value back.
View 1 RepliesI have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done
How would I create a code that can be called apon to activate but not recive or send any information through the program.And just to clarify what I mean by that is it will read information out of a textbox and write into it. But it wont actualy recive anything or send anything back from where it was called apon.
I have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this

I am designing a program to be similar to Microsoft image viewer. I want it to open on PC start up Full screen and I want to make it scan for Images on flash drives with the user doing anything. I am making a Digital Picture frame out of my old dell laptop and I would like to make the program for it. How to have it play a random image every 30 seconds or so...

I have an existing vb.net application which uses a home grown database. The database has over 60,000 unique multi-field records in it.The user can search in each field using drill-down to find a record, and then can add that record to a separate database.(60,000 collectibles described in a master database. User can drill down by category, manufacturer, year produced, etc. to find a record and then add it to their own 'collection', 'wanted', 'have for sale', or 'spares' database for record keeping.)
Instead of having them drill down, I would like for them to be able to perform a search and have all of the results (any amount of matches from 1 to 60,000+) appear on a scrolling form with a checkbox next to each so that they can simply check any that they want and do a mass add to their list databases.
The part I cannot figure out is how to have vb.net (2008) create a variable length scrolling form with the results, and how to identify the checkboxes (generated by the system for search matches) to see which, if any, have been checked by the user.
It seems difficult to find good information on working with bitmaps. Specifically I am looking for .NET info on getting tile graphics to the screen. What I know so far is this. I need a picturebox for the display. I need a second picture box for a back buffer and then I need a third picturebox for the tiles that I would copy to the back buffer which then gets flipped to the screen.I need this to be done with .net controls and classes or functions and etc. If anyone has good information on this, please let me know. I am using visual basic 2008 express edition.

I recently found an awesome tool called "Freemind" that is called a 'mind mapping' program. It's similar to MS Visio but way cooler and more automated.I reeeallly would like to integrate this into a VB.net Form, but how?
Has anyone seen or heard of mind mapping inside VB.net before? Are there programs out there already that work with VB.net or anyone have an example they have seen / built that works?

View 2 RepliesI have a function to pull data from a XML, and to report a specific number based on a value in one of the elements in the XML. Unfortuntately, I can't get any break points to work, so I've been debugging with a trace.he strange this is that when i take out the function itself it works like it should, otherwise the Service freezes when it gets to the function and never uses it. I'm calling the function in while loop which is also within a Try Statement, here's example of the code.

Hows it going. Im in some need some help. Im trying to make a Program called process master, and one of it's features is When clicking an item in Listbox1, It will show on the side in Label 11 the path of that process.

I'm writing a program and have run into a bit of a snag. I have the code perform a button click on certain buttons, the reason for this is I have a bunch of buttons that each do something and one that does everything automatically. I suppose I could rewrite everything under that one button but that would essentially double the size of my program, I could use an if statement to catch the fact that the program is in automatic mode but that would be about 15 conditions (not looking forward to writing that statement ;p)
Clicking the buttons is a nice simple, clean solution. The exception being the program performs the click then continues on executing the rest of the code in the actually clicked button while at the same time executing the code called by the code click. Main problem with this is the data that needs to be populated by the code click isn't being populated fast enough for the code in the main button so then there is errors, blank data, program doing nothing. A simple sw timer to delay could work (I know how to make one of those) but the problem with that is the program is executing against a webpage and if the webpage takes a few seconds longer to load then anticipated everything is out of wack again. I'm looking for a simplish way to cause the program to wait for ALL code called by any raised event to finish before proceeding.
i.e. Call Button.clickEvent > Wait for code and subroutines executed by Button.clickEvent to finish > continue with rest of code in button.
Below is the code I'm using so far for the user clicked button.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Button4.PerformClick()
'Need to wait for all code executed by Button4 and anything it calls to finish
x = 0

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

i'm creating a program called Workshop Selector. It has 3 list boxes, one with the 5 workshops, second with 6 locations, and the final is the list of costs. The user selects a workshop, a location, then hits the Add Workshop button, which calculates the costs and adds the cost to the third listbox. Soo, to my question.
There is an additional button called Calculate Total that adds the values of the costs in the cost listbox and displays the total in a textbox. The code i currently have that works just fine is --
Dim one, two, three, four, five, total As Integer
lbCost.SelectedIndex = 0
one = CInt(lbCost.SelectedItem.ToString)
lbCost.SelectedIndex = 1
two = CInt(lbCost.SelectedItem.ToString)
etc..etc..
total = one + two + three + four + five
tbxTotal.text = total
While this works, i have no idea of knowing how many times the user will add a cost to the cost listbox. therefore id have to make many many variables, and other issues occur.So is there a way i can do this with a for loop? declare a global variable like
Dim costcounter as integer
then at the end of the add workshop cost btn click procedure use:
costcounter = costcounter + 1
That way i kno the exact amount of times the person added a cost?
Then create a for loop like
Dim intcount As Integer
For intcount = 1 To costcounter
code....
Next
Would this work somehow? but what code would i have to input within the for loop to scan each selected index, and then return values that can be added together and displayed in a textbox?
Ok ive managed to figure our most of my problems, and get help , from u nice people. i have 88 buttons and 1 is visible by default the rest are invisible so if you click the first button you get a open dialogue to select a program for my app called winhome after that i need the second button to become visible, and so on,any quicker way to do this instead of manually copying/pasting if statements?

I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?
View 4 RepliesI'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
Is this where i would post a picture of my interface and get feedback on changes for easier use? If not is there someplace on this forum or any other forum to do this?
View 1 RepliesSo I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
Ok I have this: This makes a sub called 'graphicspaint' then writes "demo version" to a picturebox1
