that´s OK, but there is a little problem: I don´t use any dataadapter or real database. I read data directly do the Dataset from XML. (DataSet.ReadXml('mydata.xml'))

Certainly there are many approaches. If your application doesn´t rely much on speed, you could scan each line in the image and make a histogram from which you then compute some values like median, dispersion or something like that. But you have to decide what to measure: amount of contrast...

you can create an ellipse class that would hold the position, color, tag or some other info about the point you just clicked. After clicking you could add the instance of this object into an array. On mouse move you could iterate through al the elements in the array to check which ellipse the...

Does anyone use TestComplete to make automated tests? Do you like this tool?

it depends on wether you draw something onto the picturebox using gdi+ or you are just assigning an image to the picturebox. In case you use gdi+, you can use transforms (scaletransform) to scale up/down everything that is drawn afterwards. The coordinate system gets scaled, but if you use the...

I have 2 tables in my dataset: - Items - Warehouse The Items table contains a column named 'WarehouseID'. It tells me which warehouse this item belongs to. The Warehouse table contains an 'ID' column and a 'Name' column. Now if I display the contents of Items table in a datagridview I will...

OK, I tried it and it seems to be working perfectly. You can see the original path drawn with black line and the flattened path drawn in red on the appended image from my application. I´ve increased the flattness value to 10 to verify if it really works. I also took the next step and used the...

Hi, I wonder if there is a way I can get the REAL bounding rectangle for a graphicspath, for example a path consisting from one or more bezier curves. The bezier curves in the path have control points and the function .GetBounds takes these points in account. But I only want to get the bounds...

Let´s say I have an array (I named it "Points") of objects. Each object has a custom property called for example "Selected". The property type is Boolean. Can I use LINQ to determine the INDEX of the element in the "Points" array where "Selected=True"? (I´ve ensured that only one element can...

If you prefer Visual User Interface Testing, then I would suggest TestComplete. It can run automated tests for VB6 and .Net applications.

Just use ContextMenuStrip that shows up in a proper position when the button is clicked and you could add some image to the button that changes on MouseOver and MouseClick.

Hi, is there a way to make a user control (similar to panel) that has a custom container area? Ordinary panel has a container area that is almost the same size as the panel itself, and I don´t know a way to change it. The new control should have a container area (where I can place other...

Hi guys, I found it at last. I can get the column bounds using: DataGridView.GetColumnDisplayRectangle(ColumnIndex, CutOverflow) This function returns the bounding rectangle for a column specified by index.

Hi, I know how to set sorting direction on each column in datagrid programatically, but I wonder how to do the opposite: obtain the sorting direction for a particular column. Does anyone know? Thanks

Hello, I have a datagrid in my project and I want to place label controls above each of its columns and those labels should stay above each column even when I resize columns. I need something like "Datagrid.Columns(i).Left", but of course there is no such property. Is there a way to obtain such...

thank you for the tip, I´ll give it a try

Hello there. What I am breaking my teeth on right now is this: I have a simple database application that shows data using a datagridview. This control is bound to a DataView (so I can apply filtering). The Dataview is bound to a DataSet which is then filled from a DataAdapter using Fill method...

Tom, you were right. The records count is only rising but never declining. So I simply placed: DS.Tables(0).Rows.Clear before the fill and it works great now. Many thanks ;)

I decided to rather resize the label in code, because there are other controls to the left of the label. Thank you anyway ;)

Hi, I have a simple but tricky problem: I have a label inside a container control (form, panel, or whatever). The labels anchor is set to bottom & right, auto-size is set to true and the textalign property is set to middle right. The length of the text changes during runtime. I want to ensure...
