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.
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.
How can I set up an application wide event trap that is triggered when my database connection status changes?i.e. no matter what form the user may be on if the connection is terminated for whatever reason a message box is displayed to the client requesting whether the program should try and reconnect with the database or not.
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] .....
Has anyone used a system wide hotkey and notice it no longer works? But the program is still running fine. When I run my program and it starts the hotkey, sometimes it will work fine all day, other times within 15 minutes I press the keys and the program does not react to it. I am using the keys Control-F2. Here is my
Public Sub SetHotkey() Try Select Case ComboBox2.SelectedIndex
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?
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
In times past, most people coded on a terminal that was 80 characters wide. In many languages this has become, if not holy then close to it. But now many people have 20"+ monitors (or dual monitors), so screen real estate isn't as prime as it once was.
So my question is this: in Visual Basic code, should code be limited to 80 characters, should there be no limit, or is it really a subjective thing, dependent on where you work and your own preferences?
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?
I am developing an application that has multiple forms and I wanted to know the best method to have application wide methods and functions. Currently I am using a Module with all my methods that are needed to be used across the entire application in it. However, I read at one point that modules should not be used, as they are only there to preserve backwards compatibility with older VB code. Is there a better way to have methods able to be called anywhere?
i've managed so far to get a global mousehook + i'm hoping to capture the selectedtext from anywhere system wide when the user left clicks.
i tried using the keybd_event api to send CTRL+C to copy any selectedtext to the clipboard but it has unexpected effects + seems to run before the text i've just selected becomes selected.
here's the code i'm using:
Public Class Form1 Private Declare Function keybd_event Lib "user32" Alias "keybd_event" _ (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Integer, _
I'm trying to open a tool window as a child and although I can set the width to something like 50px wide in the ide, when it opens up its 125px wide. What is there to opening a widow with out much width am I missing.I have turned off the maximize and minimize gadgets and even the whole drag bar. When they open up when I run they are fat again. Looking for something like the tool window in paint.net.
I am after some GDI+ help, Basically I have an LED display which for example is 300 LEDs wide by 300 LED's deep, so you could say it has a resolution of 300x300.I am intending to use windows to process images ready to be sent to the display (as the display is dumb and simply displays what it is sent, But I require that the images are animated as well as static sort of like the basic PowerPoint animations (scroll on/off etc).to achieve this I need to write some code that creates frames much like gif's. So to scroll a 300x300 image onto the display I would need 300 separate frames.
So I have written the following code that uses the GDI+ objects to build the frames needed to scroll an image from the right or left.
I'm looking for a windows "special folder" where user data can be stored and changed PC wide, not only per user.Up to now I've picked the so called COMMONAPPDATAFOLDER, but that doesn't work with a setup project, because the files copied there on installation (like a config file) are not changeable in Vista with a program used by a restricted user (probably because the Windows Installer performs with admin credencials).
Currently I am able to see if a key is currently pressed via the GetAsyncKeyState function. Currently I just simply have a timer running in the background that constantly checks if a certain key is pressed in order to run a command. However my issue is if the user holds down the key it will continually run that bit of code over and over per timer tick. Is there a way or another function to detect a keyup or keypress only. This is my current code to detect keys:
Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Windows.Forms.Keys) As Integer Public ReadOnly Property CurrKey(ByVal key As Windows.Forms.Keys) As Boolean Get Return CBool(GetAsyncKeyState(key)) End Get End Property
i need to store Application wide Settings in my Application like:
Connection to DB (Servername) Username/Password Registrar/Serial etc. I think there are basically two Options:
Store them in the Registry Store them in an Application Settings File Using one of the methods above is no problem, but under Windows 7 my Application running in normal user mode allows me only to store user specific data. For example inside UserAppDataRegistry, UserAppDataPath etc.
But when i want to use e.g. CommonAppDataRegistry to write my Data in, then i get no access to it, due to missing privileges.
Now my question:
Where and how to store Application Wide Data? How are others doing this? When i purchase an application and install it on my pc, it asks me for Uusername and Serial. When i insert it then it saves it somewhere without asking me for Administrative Privileges or something else.
I have a license form that i wish to save the information or just system wide information for that matter,I know about the my.Settings - however this will only save for a specific user and the aplpication scope you can not write to.Where is the best place or the normal practice of saving application wide information?
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.
I've been looking at using PROPERTIES [URL] but frankly I don't understand it that well. Before I invest the time to read, understand, and truly comprehend this, I want to make sure it's the best way. My intended goal is to create my database connection string in a function/sub somewhere, then assign it to this project wide string variable, then I can use it in any form, project wide without having to recreate it.
I have a dropdown list box that displays data from my database. Problem is that some records are quite long so the width of the dropdown box extends past the side of my screen. I have a reasonible width set but it is not stopping the dropdown box from getting as wide as it needs to display each record. How can I set a fixed width on this?
I want to make a user control (name MultiSelect), which I will use for choosing items from huge list. For example I want to choose customers to make a view of their turnovers, so I will creat a new MultiSelect control which will contain a textbox (i canwrite starting letters) and a treeview (will list customers matching the first letters chosen in textbox).
We are translating UI of one VB6 application designed in English (US) into Chinese Language which contains API's, we need to know how to use the Unicode (Wide) versions of used API for new (Chinese) Language and how can we find is there any wide version exist for that used API and how to modify existing API with wide API.
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 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".
