InTouch and MS Excel CommunicationsIs there a way to use it in a more generalized way? If I want to set up a table with different FX pairs e. I have tried e. Then, whilst this cell is still selected, enter the same text into the name box adjacent to the formula bar on the excel ribbon. Thereafter, instead of writing the full formula, you can refer to the named cell after you have typed the "! I have made this short video to explain my point. Hope this is clearer! I think he wants to and so do I be able to alter the contents of a cell and then what is written in cell is used in the DDE request. If I understand you correctly, you want what ever you type into a cell to be added to the part of the DDE formula reserved for the name of the currency pair. I assume that you would like to be able to do this so that each DDE formula would be updated whenever you change the text content in the one cell that you would use for naming the pair? If so, then I am afraid that is beyond my knowledge of Excel. As far as I am aware, you can only name the cell as I demonstrated because the DDE formula is only interested in the name of the cell and not the contents of the cell, indeed the cell could be empty. Perhaps there is a way with VBA coding Sub SetUpTable Cells 1, 1. Value Cells iRow, 3. Value Cells iRow, 4. Value Cells iRow, 5. Value Cells iRow, 6. Value Cells iRow, 7. Value Next. To use, create this in the VBA editor and attach it to a shortcut key, then whenever you press the shortcut key combination it updates the table. I exported the market watch window in the MT4 application. This creates a '.

Getting Started with the TWS DDE for Excel API Webinar Notes
Keep in touch and stay productive with Teams and Officeeven when you're working remotely. You can use the DDE function to initiate a dynamic data exchange DDE conversation with another application, request an item of information from that application, and display that information in a control on a form or report. For example, you can use the DDE function in the ControlSource property of a text box to display data from a specified cell in a Microsoft Office Excel worksheet. DDE application, topic, item. The DDE function syntax has these arguments:. A rgument. A string expression identifying an application that can participate in a DDE conversation. Usually, application is the name of an. A string expression that is the name of a topic recognized by application. The topic argument is often a document or data file. Check the other application's documentation for a list of possible topics. A string expression that is the name of a data item recognized by application. Check the other application's documentation for a list of possible items. The DDE function attempts to initiate a DDE conversation with the specified application and topicand requests the data in item. If successful, the DDE function returns a string that contains the requested information. If you are requesting data from Excel, item might be a row-and-column identifier, such as "R1C1" or the name of a range of cells. In the following example, the DDE function requests information from the cell at row 1, column 1 in an Excel worksheet. You can enter this expression for a text box control in the ControlSource property box on the control's property sheet:. You can use the DDE function only in the ControlSource property of a text box, option group, check box, or combo box. For example, if you use the DDE function in a text box, the text in the text box can't be edited. You must edit the text in the other application. Because the ControlSource property is read-only in Form view and Print Preview, changes to the control must be made in Design view. Microsoft Windows and your computer's memory and resources determine the maximum number of DDE conversations that can be open simultaneously. If the conversation can't be initiated because the other application isn't running or doesn't recognize the specified topic, or if the maximum number of conversations has already been reached, the DDE function returns a Null. If so, the DDE function returns a Null. Similarly, you can set Access to ignore requests from other applications: click Access Options on the File menu, then click Advanced in the Application Settings dialog box. If you need to manipulate another application's objects from Access, you may want to consider using Automation. The following table illustrates how the DDE function behaves when you use it with each of the controls. Con trol. The item argument can refer to text or numbers. If item refers to more than one piece of information, such as a named range in an Excel worksheet that contains multiple cells, the DDE function returns the first entry. You could use this function with a text box to display the data contained in a cell on the worksheet. The DDE function fills the combo box with the information referred to by item. You can't enter data in the text portion of the box. The OptionValue property of each option button in an option group is set to a number. Usually, the first button value is 1, the second is 2, and so on. The number returned by the DDE function determines which option button will be selected. For example, if the DDE function returns 2, the second button will be selected. If this function returns a value that doesn't match any of the OptionValue property settings, none of the buttons will be selected.
