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?

View 4 Replies View RelatedI 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#

View 5 Replies View RelatedI don't know coding to Insert data in sql with C# language and I want to save data with the click event of save button
View 4 Replies View RelatedI have:
An Access database in which the picture right now is saved by its directory, together with other field like title, publisher, developer,..
Visual Studio form in which a load button gets that directory as text
Details button that reads the ID of a selected item (I have a list of games) and displays the corresponding picture by reading the directory
The problem right now is that once someone else opens the program on his/her computer, the directory changes, making the whole thing useless.
Is there a way to get around this problem? The books I've been reading don't really adress this.
Directory is a string in class 'Game'; it's short text in the database

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.

View 2 Replies View RelatedI have an application which inserts large amount of data in Access database. So to speed up the things i have set Indexed property to No.
So at the end of insertion i need to set the index to the column of the one of the table to Indexed (Duplicates OK) through C#.
I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.

I have an extremely annoying problem, I am inserting data into an access database and now i have noticed that it is copying itself to the bin/debug folder on ts own and yet i have set "Copy to Output Directory" property to "Copy never"
But without fail, it is copied! It is making any attempted updates to the database's information invalid since its not updating at all.
This all started when i installed crystal reports and it asked me to make a duplicate of the database in order to utilize data-sets that were created for certain reports.
Why this is happening? I cannot test my application properly at all.

View 4 Replies View RelatedI m making calendar in server control page by taking composite control.I am also adding textbox in each cell of calendar. Now i want to access the value of each textbox of selected month and respected date in default.aspx page on button click event. Here the button is not a custom control but defined in default.aspx page..
Can't access textbox text and date or controls of server page in website(default.aspx) page.
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)
if we don't provide the acces modifiers for base class and we need to manipulate the private data of base class in derived class. Is there anyway to acces the private data members? Here's a coding example
class A {
private :
int a;
};
class B : public class A {
public :
void displayA() { cout<<a<<endl; }
};
how i can acces the a of base class A in derived class B without acces modifiers.
