  • MultiCast Messages to multiple clients on the same machine

    - by Christopher Chase
    Im trying to write a server/service that broadcasts a message on the lan ever second or so, Kind of like a service discovery. The message needs to be received by multiple client programs that could be on the same machine or different machines. But there could be more than one program on each machine running at the same time. Im using delphi7, with indy 9.0.18 where im stuck is if i should be using UDP or IP MultiCast or if its even possible... Ive managed to get it to work with IP Multi Cast with one client per machine, but even after many trys with different bindings.. max/min ports etc, i cant seem to find a solution.

  • Changing Positions of the Chart When Creating Multiple Charts Automatically via Vbasic in Excel 2007

    - by McVey
    I am creating a new chart for each row of data in an Excel spreadsheet. I have the Vbasic working properly, but I want to change the position of the chart on the sheet that is added for each row. Below is my code, what do I need to do to change the position of the chart on the page automatically? Ideally, I would like it to be in the upper left hand corner of each sheet. Sub DrawCharts() Dim Ws As Worksheet Dim NewWs As Worksheet Dim cht As Chart Dim LastRow As Long Dim CurrRow As Long Set Ws = ThisWorkbook.Worksheets("Sheet1") LastRow = Ws.Range("A65536").End(xlUp).Row For CurrRow = 2 To LastRow Set NewWs = ThisWorkbook.Worksheets.Add NewWs.Name = Ws.Range("A" & CurrRow).Value Set cht = ThisWorkbook.Charts.Add With cht .ChartType = xl3DColumnClustered .SeriesCollection.NewSeries .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" .SeriesCollection(1).Name = "=" & Ws.Name & "!R" & CurrRow & "C2" .SeriesCollection(1).XValues = "Sheet1!R1C3:R1C8" .Axes(xlValue).MinimumScale = 0 .Axes(xlValue).MaximumScale = 1 .Axes(xlValue).MajorUnit = 0.2 .SetElement (msoElementDataLabelShow) .SetElement (msoElementLegendNone) .Location Where:=xlLocationAsObject, Name:=NewWs.Name End With Next CurrRow End Sub Any help is appreciated.

  • excel 2007 vba: how to refer to HPageBreaks

    - by notnot
    I'm trying to write a macro which can look into the list of horizontal page breaks that a worksheet keeps, and it seems like HPageBreaks should be exactly that. I can add or remove page breaks from it, but I can't seem to isolate the collection itself to look at its contents. Even adding a watch and looking at ActiveSheet.HPageBreaks just brings up a generic looking object with a count field equal to 0 regardless of existing page breaks. I'm really confused about this now. Is there any way to look into the existing page breaks within a sheet? A listing of what rows they occur on/between would be great.

  • Public-facing SharePoint 2007 portal - authentication question

    - by jdcorr
    I am involved in developing a portal with a public-facing side. For this i created a web application with windows authentication for intranet zone and after that, I created an extension for an internet zone with fba. In the internet extension we have the following requirement: - able to acess to sharepoint backoffice using fba. - have a authentication mecanism for portal visitors, where they can authenticate and acess to a page where they can subscribe the newsletter and define some site appearance (this users can't acess to sharepoint backoffice). My idea is use the aspnet membership provider to authenticate both users and create diferente roles for them. Anyone suggests another approach? Is there any way to ensure that visitors (2 case) do not enter the backoffice portal? Thanks

  • Access 2007 VBA : Building a listbox with selection choices from another list box

    - by Justin
    So there are 8 categories that may be associated to each order, but not necessarily all of them. So i was going to build a list box that allowed the user to double click each of the category they wish to associate when they have an "Order Detail" form opened up (unbound form that has hidden text boxes with all needed ID numbers). I want to have another empty text box right beside it that will allow me to append the selections (up to 8) so the user can see that they have been added. So one list box with the default choices, and when a choice is double clicked, it adds that choice to the second list box to see the tally so to speak. What is the VB for getting something like this done? Thanks Justin

  • How to show scrollbars in TScrollBox after it has been made visible again?

    - by aleluja
    Hi, I've ran into one small problem. I am dynamicaly generating some controls and place them on a TScrollbox component. But i noticed that if scrollbox is visible, user can clearly see each of the controls being created and placed. So it looksl ike lots of work is being done and it is slow. I hid the scrollbox and generated all the controls on it, which took much less time and no flickering and alike. But here's the problem. When i unhide the scrollbox, its' scrollbar doesn't appear untill i actually resize the form. (The alignment of scrollbox is alClient) Any ideas on how to fix this? Tried repainting, but it didn't work. Refresh didn't work either. Thank you

  • MOSS 2007 - Using Connectable WebPart - Consumer has TextBox

    - by JohnP
    I have 2 webparts which are connected, where the provider sends a string to the consumer. However it fails to work if I put any TextBox controls in the consumer webpart. (works fine if I use a Label or Literal control. The idea is that the consumer is to be composed of form controls like TextBoxes. e.g. the codeproject sample at http://www.codeproject.com/KB/sharepoint/ConnectingCustomWebParts.aspx Works fine... until you replace the consumer Label control with a TextBox. Any help gratefully received.

  • How to make this OO?

    - by John
    Hello, Sorry for the poor title,I'm new to OOP so I don't know what is the term for what I need to do. I have, say, 10 different Objects that inherit one Object.They have different amount and type of class members,but all of them have one property in common - Visible. type TObj1=class(TObject) private a:integer; ...(More members) Visible:Boolean; end; TObj2=class(TObject) private b:String; ...(More members) Visible:Boolean; end; ...(Other 8 objects) For each of them I have a variable. var Obj1:TObj1; Obj2:TObj2; Obj3:TObj3; ....(Other 7 objects) Rule 1: Only one object can be initialized at a time(others have to be freed) to be visible. For this rule I have a global variable var CurrentVisibleObj:TObject; //Because they all inherit TObject Finally there is a procedure that changes visibility. procedure ChangeObjVisibility(newObj:TObject); begin CurrentVisibleObj.Free; //Free the old object CurrentVisibleObj:=newObj; //assign the new object CurrentVisibleObj:= ??? //Create new object CurrentVisibleObj.Visible:=true; //Set visibility to new object end; There is my problem,I don't know how to initialize it,because the derived class is unknown. How do I do this? I simplified the explanation,in the project there are TFrames each having different controls and I have to set visible/not visible the same way(By leaving only one frame initialized). Sorry again for the title,I'm very new to OOP.

This applies even with a simnple =[Modified] formula The Server is set up in the US for that locale.
