I am facing the problem of adding the image in MS Access Database. I know that OLE Object datatype is used to insert the image in MS Access database.
I have already converted the image in Byte form but unable to add that Byte [] to OLE data type.
Is Byte compatible with OLE Object Datatype?
I have 3 columns already made Product, Price, Quantity, - what I want to do is take the textbox's txtName, txtPrice, txtQuantity, and add them to the columns in the right specific places.

What i'm trying to do is load an image from my database create some graphics to it. probably just some lines and marks and save it back to my database. here's so far what I got.
for creating graphics:
} private void pictureBox3_MouseDown(object sender, MouseEventArgs e) {
draw = true;
} private void pictureBox3_MouseMove(object sender, MouseEventArgs e) {
if (draw) {
Graphics g = Graphics.FromImage(pictureBox3.Image);
[Code] ....
but the saving part doesnt work :( I think it only saves the image loaded to the picturebox but not the graphics created to it. how to merge it? i've tried to google it and found some sort of same cases but fails to make it work, something like converting it to bitmap.
Is it possible to save web page as image with web application? if yes then how?.I searched and searched and searched but all examples i found were for windows application and i'm facing lot of trouble while converting it for web application.

I have a .png file that my console app reads and puts into a structure that is saved as a file. The png is always the same so I thought I could just add it as a resource image to a resource file so it would be included in my program and not as a separate file. When I did that, the png shows up as a "SystemDrawingBitmap". If I examine this resource in a watch I see "Base" and "Static" members. Expanding those properties does not give me anything useful such as a pointer to the raw png data and its length in bytes.
If worse comes to worse, I can always make a hex dump of the png contents and then put the hex code into a CS file using static initialization.
Surely there is some way I can access the raw data internally and read the bytes into a byte array using C#
how to insert a variable for the size of array and prompt user to insert the elements for the array?

at the moment I lack access to the pc with the code on it, so for now I will try to keep my question basic.
now here is my problem: I have a listview witch is populated by user input(lets say for the ease of argument that the input is "first-name" "last-name" and "e-mail adres") all of with get there information from textboxes.
then all the information gets stored in a list and on closing that list is stored in a xml-file in the following format
<Root>
<Data>
<first-name>
Samual
[Code].....
the input, saving and loading is no problem. when you open the file this listview is in view = List so that you only see the last-name(I prefer it that way since I know how to code that) and when you click it it fills the textboxes with the corresponding information.
what I am trying to figure out it how to make it that it sorts itself(preferred sorting when something is changed).
I tried the ListView.sorting = SortOrder.Ascending; when I do it that way it messes up the corresponding information(is it clear what I mean or do I need to add an example).
Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)
I was using the same item click event on another listview, and it worked perfectly... I don't know why this is happening, but here's my problem:
When I double click on an item, and try to obtain its index in the listview, the items index always comes back as -1... Obviously -1 isn't an index, and I'm guessing that it is returning -1 because that item does not exist on the listview, but from what I'm seeing, it is impossible for the item not to be inside of the listview...
Here is the xaml for my listview:
<ListView x:Name="lstBookmarks" HorizontalAlignment="Left" Height="250" Margin="10,10,0,0" VerticalAlignment="Top" Width="327" ItemsSource="{Binding Bookmarks}">
<ListView.View>
[Code]....
When I uncomment the MessageBox, it shows -1... This is obviously not right lol. I have the same exact click event in another class, and I obtain the items index the same exact way.. The only difference between this listview and that one is that this listview is databound.. Is that the issue? If so, how does one overcome it?
i have a list view, which is shown below as an example, i am hoping to achieve to find out a method of adding up the values in the Sub2 Column in C#. Then i will output it to a label on my form. So the total should be 14. But i don't have a pre-defined number of rows, and thats what i needs to be. I thought of something like
label1.Text = ListView1.SubItem2.text
But no such luck....
Index Item Sub1 Sub2

Is there an easy way to create a column of buttons ina listView?
I need that every file of the listView has a button in the first cell. Is that possible?
If we work with a ListView,and want implement some functions like OnLBDblClick(), we only have a CPoint, but not the column and row that this point suppose. How can i Know that, is there another type of functions that gave us the row and column?
View 2 Replies View RelatedI've been trying for a while now and I can't seem to replicate this model without using a grid. I've tried making some simple custom panels and a wrappanel that makes a new column after n pixels or n number of items which works; however, I'm unable to find a way to stagger each column.
Here's an image of what I'm trying to do:
enter image description here
I've made solutions that use a Grid that do stagger the columns however what I need is a panel that uses columns only and it must be able to be used as the itemspanel for a ListView.
I'm using listView to show content (selected item) in ComboBox, TextBox, Labels..
I was using
DropDownStyle = DropDown
and actually i use DropDownStyle = DropDownList.
With this change,
comboB.Text = Name;
stopped working correctly (onload), only work after first click any item. Why?
I tried too
private void comboB_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
but with copy/paste with mouse i can add text in ComboBox.
PS: My objective is combobox no editable.
