after numerous google searches and comparing excerpts from different peoples' various codes I could not get this program to work, though I came quite close. I'm attempting to make a program that will tell me the time in different parts of the world, a personal use program that I thought would help me exercise my vb skills.
The problem I'm having, however, is that when it should be showing my time it is either 5 hours ahead or 5 hours behind. I tried adding variables and deleted them again time and time again trying to make adjustments but all I managed to do was make the timer get stuck at 12:00:00 AM.
I am having a problem trying to get a real time back from this code.
Code: Public Sub Time() Dim StartTime As TimeSpan = TimeSpan.Parse(txtStart.Text) Dim EndTime As TimeSpan = TimeSpan.Parse(txtEnd.Text)
[Code]....
I am using a start time of 09:25 and an end time of 10:15 to test this with. I would like it to return 50, as 50 real world minutes went by. I am getting -1331385.
This is mostly someone else's code from a different forum. I have never used a TimeSpan method before and they keep telling me it works "like what I asked for".
I have a lot of HD images within my program design and it is causing the screen to flicker when loading other forms. It is kind of slow too. Is there a way to resolve this, for example, using a reference or component such as DirectDraw. Here are my computer specifications:
Intel Pentium 4 /2.53GHZ 1.5 GB RAM 512 MB ATI Radeon HD 2400 PRO AGP Video card 19 IN. LCD Widescreen 1440x900 resolution monitor.
The 3rd sub below (WorldMapViewer1_AreaMouseClick) handles "e.Area.Name" just fine. But I need my 1st sub ABC() to pick up the same "e.Area.Name" information and pass it to the 2nd sub LoadStateIndex() before anything is done in the 3rd sub.
Private Sub ABC() LoadStateIndex() End Sub Private Sub LoadStateIndex() [Code] .....
i saw in many website that there's a combobox that display all the world countries to choose one of the country as your country.so i want to do this in program.is there any class or library that have all the world countries and then i add them to combo box?or do i need to enter them manually?
i am new to VB and am trying to make a metric to imoerial unit converter in VB 2008. I have created a form with 2 list box's with MM, CM, KM etc ....... and the other Inches Miles etc I have added 2lables with convert from and convert to and also 2 blank text box's the first one to choose the number i would like to convert and another to show the converted unit, I have also added a convert button.I am really struggling to find the correct code to make this work.
So i decided to make a units converter for my term's project and my teacher insisted on including the combo box in this project. I'm not really familiar with the combo box as i am still a beginner in visual basic. I've looked around and learned a bit about using the combo box but later i faced a problem. First i created a Main combo box and placed it in the middle of the form. I managed to use the select case command to make other combo boxes appear and disappear as i wish. I don't really know how to describe the problem, i want to make it that if i choose the input as a unit and the output is any other unit from two different combo boxes, the value in the input text box would be multiplied by a certain conversion factor and the result will be shown in the output text box.
I'm trying to create a program that takes 7 numbers and converts them to Letters. To do this I have created a TextBox to enter the 7 digit number in , a CONVERT Button, and a LIST BOX to display the thousands of results. This is created using a Windows Application Form.
At the moment im tryng to create a celcious to fahrenheit i already got the formula and so i put it into visual basic. My goal is to create a programm with two textboxes
one celcious and the other one fahrenheit.[code...]
THen i realized that loop is created because if i write 12 in celcious it outputs to fahrenheit which outputs back to celcious ecc.. infact when i debug it says
Make sure you do not have an infinite loop or infinite recursion .I would like to have a programm with 2 textboxes. If in one i put 12 then the respective fahrenheit comes out; If in fahrenheit i put 55 then the respective celcious comes out.
I'm a bit new to these forums but anyways let me get to the point. I'm trying to make a Unit Conversion Program on VB 08 and I am trying to make it so I don't use too many radio buttons, however I may use it if there is no other option. And I also have to make the program do it both ways
For Example I want to convert Fahrenheit to Celsius and Celsius to Fahrenheit in the same textbox or some sort of box.
I'm trying to make a simple character converter i.e. (A converts to O) or (C converts to V) I need to make defined parameters for the entire alphabet.I have two text boxes set up and a command button. I'm trying to make it so the text inputted into the first textbox is converted (using the defined parameters) Into the second textbox with a click of the button.
error: Conversion from string "The world is veiled in darkness." to type 'Double' is not valid.
If Label1.Text = 8 Then Label2.Visible = true End If
im trying to make label1 .visible = true when label5.text = 8 i set the properties to label1.text to false so when the counter hits 8 it turns label1.visible = true
how can i make a world map that moves with the cursor and ifor example if i press on asia another page will open for asia's map and the same thing for allwith visual basic 2005?
Im new to this and im currently teaching my self how to code using "sams teach your self C++ in one hour a day" (of course ignoring the 1 hour a day part!)
I have some very rusty C++ and lots of C experience, but have done little OO design or coding.I've started learning C++.NET as that seemed to be the best starting point.I've hit restrictions in Microsoft's provision with multiple inheritance and extensions, neither work in C++.Would I be better off starting again with C#, or am I better off using a mixed language approach. eg. extensions in C#, rest in C++?I'm still struggling with this->method or that.property and theother::staticthingy or whatever, and this probably is not an issue in C#. You'll see what I mean as that probably isn't the right way to desribe the difference between '->' '.' and '::'I'm getting to achieve what I want, but it's taking me 10 times longer than I think it should.
Anyways, i have coded a video downloaded and i want to include a converter as a separate exe file. But obviously people may have different file directories so a simple piece of code i have used won't work. This is what i have: Also where would i place the exe file?
Does anyone have a nice sample of a unit convertor handling multiple unit types that I can integrate in my application? I have found this one, but it is only handling one type of unit. For example I want to convert weight as well as volume from and to imperial units.
I'm just curious that how a month is calculated in the rest of the world because Differences in Months between two dates are calculated differently. In our Insurance Company, we calculate a month as below:
At the minute I can display the mouse position using Cusor.Position.ToString() but my screen resolution is widescreem - 1360:768. What about about someone with a standard 1024:768? If I use my application on other computers, it won't work because it deeply depends on mouse co-ordinates
I am aware of a world coordinate system (or something) that will work on all screen resolutions. To use this (which I will need to) I will need to change all of my coordinates in the code? So I'll need to display it in a text box like I did with Cusor.Position.ToString() but what code can I use to get the world coordinate?
There is something like PoibntToScreen and PointToClient but what do these do exactly and how do I use them? I tried using
Code: MouseCoordinates_tssl.Text = "Mouse Coordinates: " + "{X:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).X.ToString + "; Y:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).Y.ToString + ";}" but much to my disappointment, it didn't work. What could I do that would work?
I know how to calculate a city's location on the world map by using its geographical coordinates as a pixel on the map but how in .net can I draw a link with a cuve? Once I have the curve does anyone know how to determine where the curve should be for the shortest route?
I need a start date, a Total time passed until now, an average time per step, and a estimated time to finished. How can I do that? Also, I can close the application and when start up again I want to get the time counters as the last time, so How can I store that data is normal txt file (I say txt to take advantage of the ini app file which is a txt).
Let's say we use NASM as they do in this answer: how to write hellow world in assembly under windows.I got a couple of thoughts and questions regarding assembly combined with c# or any other .net languages for that matter.First of all I want to be able to create a library that has the following function HelloWorld that takes this parameter: Name In C# the method signature would looke like this: void HelloWorld(string name) and it would print out something like Hello World from name To sum it up Create a routine in ASM ( NASM ) that takes one or more parameters Compile and create a library of the above functionality Include the library in any .net language Call the included library function Bonus features How does one handle returned values?Is it possible to write the ASM-method inline When creating libraries in assembly or c, you do follow a certain "pre defined" way, the c calling convetion, correct?

I'm having a bit of a problem with a loop I made. So the setup is as following:We can create a routing somewhere in the world, from point A to B...and the program draws it on a worldmap.then I open a file with 300 zones in all over that country and he also draws these zones (it can go from polygons to circles. Some of these polygons are really small...when I click on a button I only want to see the zones which are connected to that routing... So I use following script:
[code]...
this works fine, but not for the very small zones...I think when he uses GetRegionScans from those small intersections...the RectangleF is so small that he thinks it's empty.
