Implement An Owner-drawn ListView In My Application Using The Code Available At This MSDN Article?
Feb 21, 2009
I'm trying to implement an Owner-drawn ListView in my application using the code available at this MSDN article, however I've encountered several issues.First of all, the double-click event only fires when the mouse is over the text in the first column of any ListViewItem. I'd prefer to keep the manual, timer-based, double-click detection routine as a last resort if possible.Second, when the ListView is scrolled sideways, clicking an item won't select it anymore.
I created an image (.png) with a transparent background and I'm trying to show it in a ListView. So I added the image to the ImageList belonging to the ListView, however when drawn, there is a partial white circle around the image. I checked and rechecked the actual image and there are absolutely NO white pixels at those positions.
how would i go about creating an ownerdrawn dtp, with highlighted dates in the dropdown + also in the collapsed view when a highlighted date is selected? i'm guessing i'd have to inherit a dtp + then handle an event or 2. does anyone have any insight or experience with this?
Ok so i have an owner drawn combobox and everything is fine in the drawitem event,except i'm a perfectionist and there is no border i have a beige backcolor, and i really just want a black border or something first i tried to draw using the given graphics and the given bounds, it failed as the rectangle was drawn oddly inside the combobox for some reason (not on the inner border, almost in the center of the combobox.then i tried the following and was surprised when it didnt work
Dim z2fx As Graphics = Graphics.FromHwnd(cmbBox.Handle) z2fx.DrawRectangle(Pens.Black, New Rectangle(0, 0, cmbBox.Width, cmbBox.Height))
then i tried this and thought for sure it would work
1 Dim zfx As Graphics = Graphics.FromHwnd(cmbBox.Parent.Handle) zfx.DrawRectangle(Pens.Black, cmbBox.Bounds)
this drew 2 sides of the border, the bottom and the right then i realized something: the code i used earlier with z2fx made the upper and left borders flicker right when i click the drop down, then it goes away. It is as if they were being redrawn with the background color of the combobox. And this redrawing was taking place after the drawitem event was called.
Something, some event, keeps redrawing the background color of the combobox when i put a button on the form and associate it with the zfx2 code, then when i press this button the combobox draws the 2 borders (upper and left) and they stay drawn until i either hover over the combobox or open the drop down of the combobox.
nvm while typing this i figured out a solution i can use the mouseenter mouseleave and dropdown events
since i typed this already im posting it anyway if i have problems i will let you know.EDIT: failed.SOMETHING keeps redrawing the damn background only after most events have passed! i tried the backgroundcolorchanged event it didnt work. this is annoying.
I tried to add icons to the items in the listbox(owner drawn listbox- variable). I m able to do it. But after adding the items, according to my requirement i need to remove few items now and then.I used:Listbox1.Items.Remove("Aqua")This removes the last item from the listbox instead of the mentioned one. the same is done even if i try to remove the selected index item.
i have an owner drawn list box which is connected to a SQL database source. When the list box is owner drawn, my list box is filled with the text "System.Data.DataRowView". When i turn off owner drawn it works perfectly.
The problem is, i need it to be owner drawn as it is a crucial part of my program. Is there a way of keeping my owner drawn list box and preview the data from the SQL database at the same time? Here is my code for the owner drawn part, most of this is irrelevant, just mainly look at the bottom bit where i print the string, with the variable 's' and 'drawstring':[code...]
I'm trying to create an owner drawn TabControl that looks like the tabs in Visual Studio on XP (might look different in Vista, not so sure).So far, I've got the background and the blueish border, and now I've run into some trouble drawing the 'tab headers' (where the text is displayed).Here's what I got so far:
vb.net Imports System.Drawing.Drawing2D Public Class cTabControl #Region " Colors "
[code]....
Why isn't this working? How do I draw a border like this around a 'normal' OwnerDrawn tabcontrol, without the funky SetStyle method..?also, the DoubleBuffer ControlStyle (in the SetStyles method) option is not listed in the Intellisense list, but it is accepted when I finish typing it... Is that a bug?
I am trying to owner drawing a list view in Tile View Mode. I am creating Items and add them in the ListView_DrawItem Event, but ListView_DrawSubItem is not firing.
I have been searching internet regarding this issue but I could not found anything relevant, the only thing I found was to call the DrawSubItem method.
I placed this checkbox named owner on my form. When i build the project i got the error as Quote: 'owner' conflicts with property 'owner' in the base class 'Form' and should be declared 'Shadows'
With all new technologies like Async/Await I spent hours rewriting sample code from the published C# MSDN Articles to VB.NET.Now that Roslyn is available, why do the authors not inlude the VB.NET code. After all, it can be converted automatically. Why does MSFT not make this a requirement fo all published MSDN articles.This would save us VB.NETs lots of precious time.
I am referring to this document on MSDN. I understand what ".BeginInvoke" does, however looking at the example code on the document.[code]The delegate myDelegate (and the DelegateMethod) accepts a control and a string, but, at the .BeginInvoke, a Label control is passed and an array.[code]Shouldn't a string be passed instead of the array? Am I missing something?
When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.
I get a message, "The MSDN collection does not exist. reinstall MSDN." When I try to access any of the HELP features of Visual Basic 6.0. I do not have an install disc for this. Is there a download or a place I can get this?
i am new to programming but love to learn new things. I decided to jump in head first and write my own program on a whim one day. I've learned what I have so far through both books and online forums and help files.One thing I can't really seem to figure out, though, is how to implement a feature into my program.
I don't know if any of you will know what I'm talking about when I say that thing I want to program is my own article spinner. I've used them before, but all of the ones I have used require me to be online. I want to design my own for offline use.
The basics are this: You write an article in a textbox. Once you have that done, you go back and rewrite various words and phrases within the article using a format like this: {word1|word2} and {phrase one|phrase 2} and so on. Click a button and it saves your article to any number of text files using your unchanged words and phrases while also choosing just one of your words and phrases within the braces and between the bars.
I found on msdn samples and modified (add Thread.GetDomaind.UnhandledException)
<SecurityPermission(SecurityAction.Demand, Flags:=SecurityPermissionFlag.ControlAppDomain)> _ Public Sub Main() ' Add the event handler for handling UI thread exceptions to the event.[code].....
hen you add for example German language you will have these files: formMain.resx ormMain.de-DE.resx formMain.Designer.vb formMain.vbIn first file you will have resources for neutral language, like strings, images, ..So now you need to add also resources for strings used in code. Add a new resource file and name it formMain.Strings.resx Then i will enter name, value pair for every string that should be translated. When you add resource file then it is automatically typed because another file with name ormMain.Strings.Designer.cs is automatically regenerated on every close of resx designer.Add another resource with name formMain.Strings.de-DE.resx. Add the same Name key's from previous resource, and just change the Value with coresponding german words. Now to access created resource from the source it will be like this
I've made a Function that will be called at the point a dataset is generated on pageLoad. The function is doing two things:
Processing the blog article and detecting any URLS in the post then converting those URLS into clickable hyperlinksCoverts all carriage returns into <BR /> tags. Although it does processes the complete article as required, including detecting all of the links, it seems that the loop to process used to detect the links ONLY detects the very first link it comes accross and every other subsequent link becomes that first link found. Clearly that isn't the desired outcome, maybo you guys can let me know how to correct this issue?
Current i'm developing an application track storage of an item.in it abusiness rule says an item can be moved to more than one warehouses. Also i need to keep the history of the Item's history, Thereefore i need to create two entities,"Warehouse" and "ItemsHistoryOfLocations". I have developped an static class diagram to show the relationshop.These are the relationship rules between the classes:
1. A warehouse could be in an Item's History of locations.
2. A warehouse could be in many Items' History of locations.therefore in the forward relationshop -- 1..*
3. In an Item's History of locations, there must be at least one warehouse4. In an Item's history of locations, there can be more than one warehouse
Therefore in teh backward relationship -- 1..* Therefore the relationship betwween teh classes is a M:N. In another Object oriented scripting languaage when ever, and M:N relationship is found between classes, their relationship is slit and put a collection class called "MemberKeyDictionaries" as the bridging entity.But in C# / VB, should we create these collection classe. IF NOT, then how should i modify my class diagram to implement this M:N relationship? and h0w do i implement this M;N relationship in code?
I am trying to implement a progress bar into my code but it seems to not run when another section of code is running. I set a timer to run when the ok button is clicked and it should then start the progress bar but also when clicking the ok button whatever radio button is selected also runs. I am trying to do this in Visual Basic 2008. I will post my current code below and I will say I am a complete novice at this so I apologize if the code looks weird:
I need to port an old Clipper app to vb.net. It relies heavily on user-written macros and indeed would be almost impossible to create without them. As VB is interpreted, I am sure it must be possible to implement code that the user has entered, but I have no idea how to do so!
We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?
I am trying to implement the following code to validate several textboxes The problem i cant figure out is once i get in an offending textbox and input the data i cant get out of it? I know i am probaly missing something simple but I can't seem to find it
HTML
Private Sub tb_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles subj_ba_txt.Validating, subj_bed_txt.Validating, subj_dom_txt.Validating, subj_gla_txt.Validating Dim errorMsg As String = "Missing Data"
To write code to implement data from visual basic into excel. Write a VB.NET program to store the following numbers into an array named �Scores�: 89.5, 76.2, 90, 86, 81, 97, 61, and 73. Your program will calculate an average score, list each of these scores in a new Excel workbook and show whether each score is below or above average. Your program will then save the Excel workbook as TestScores.xlsx.
In column A1 it should say "average" and next to it (in b1) should have the average of all those scores. in the cells below (starting from A3) it should list the scores and the column next to each score it should say whether each score is above average, average, or below average (compared to the average calculated in cell b1)
Is there a way I can have my VB application run Flash in my VB window and communicate with like the variables, objects, and other stuff in the Flash movie? Such as if I wanted to get a variable or set a variable in the Flash window.
